Systematic Review of Dimensions and Indicators in Sustainable and Smart Cities: Trends, Interdependencies, and Continental Variations

Accelerated urbanization challenges cities globally. Ensuring good quality of life and environmental protection requires innovative, data-driven solutions. Sustainable and smart cities (SSCs) offer a promising response, but effective implementation depends on selecting and using appropriate dimensions and indicators. The main objective of this article is to present a systematic review within the framework of SSCs to study trends in the use of dimensions and indicators. A citation frequency index (Q) considering quartiles is used to determine the importance of the variables considered in this study. A spatiotemporal analysis of the dimensions and indicators detected is also performed. The results suggest that the multifaceted nature of SSCs necessitates a holistic approach, with environmental (Q3 = 0.536) and social (Q2 = 0.403) dimensions being principal. Despite the lower ranking (Q1 = 0.080) of the information and communication technology (ICT) dimension, its pervasive influence highlights its evolving importance. Effective ICT implementation relies on robust social and environmental foundations, illustrating their interdependence. The governance (Q1 = 0.169) dimension is also essential for the creation of transparent and equitable urban policies. Key indicators related to energy systems (Q2 = 0.379), data analysis (Q2 = 0.327), and resource management (Q2 = 0.291) are crucial for operational efficiency and sustainability. Continental differences in prioritizing SSC dimensions highlight the importance of context-specific strategies, reflecting unique challenges and opportunities faced by different continental areas. By understanding and addressing these continental differences, policymakers and urban planners can more effectively promote sustainable and resilient urban development worldwide.

INTERNATIONAL COMMUNITY IN THE GLOBAL DIGITAL ECONOMY: A CASE STUDY ON THE AFRICAN DIGITAL TRADE FRAMEWORK

Abstract Global digital integration is desirable and perhaps even inevitable for most States. However, there is currently no systematic framework or narrative to drive such integration in trade agreements. This article evaluates whether community values can offer a normative foundation for rules governing digital trade. It uses the African Continental Free Trade Area (AfCFTA) Digital Trade Protocol as a case study and argues that identifying and solidifying the collective needs of the African region through this instrument will be key to shaping an inclusive and holistic regional framework. These arguments are substantiated by analysis of the regulation of cross-border data flows, privacy and cybersecurity.

PROGRESSO DO BRASIL NA IMPLEMENTAÇÃO DE ÁREAS COSTEIRAS E MARINHAS PROTEGIDAS COM FOCO NA META 11 DE AICHI

he rapid global loss of biodiversity has promoted initiatives to develop a global network of Protected Areas (PAs), with the Aichi targets suggesting that countries protect at least 17% of continental areas and 10% of marine and coastal areas. For Brazil, there is a knowledge gap regarding the evaluation of qualitative and quantitative objectives through practical indicators of goal achievement and effective management. This study holistically addresses the conservation status of Brazil concerning Aichi Target 11 for marine and coastal ecosystems, using systematic literature review and marine spatial coverage analysis. The results show an increase to 26% of marine spatial coverage, with greater coverage by Environmental Protection Areas. There is a predominance of studies on "Management Effectiveness," with less focus on equitable management and integration between terrestrial and marine landscapes. Indicators primarily focus on "Ecological" and "Governance" dimensions, neglecting "Social" and "Economic" dimensions. Key challenges include the need for increased financial investment, connectivity between protected areas with different social and ecological contexts, and local community involvement in equitable management. Additionally, there is a need for increased coverage of integral protection areas and standardization of qualitative assessments. Keywords: Protected areas; Management effectiveness; Aichi Target 11; Conservation policy; Coastal and marine systems.

The history of the breeding of Clematis (Clematis L.) in the M. M. Gryshko National Botanical Garden, NAS of Ukraine

Purpose. Investigate the history of Clematis breeding in the M. M. Gryshko National Botanical Garden (NBG), NAS of Ukraine, determine the main directions of hybrid Clematis breeding work. Results. It was established that the result of more than 16 years of breeding Clematis in the NBG was the selection of the 61 perspective hybrid, 42 of which, the most perspective, were assigned names. Of these, large­flowered varieties are the most numerous according to the distribution of variety groups in the current Royal Horticultural Society of Great Britain classification. In particular, Late Large­flowered account for about 40% of the total and Early Large­flowered for about 29%. Small­flowered hybrids make up the smaller part, of which about 26% belong to the Viticella group and one hybrid (‘Sputnik’) to the Integrifolia. The known directions of distribution of hybrid Сlematis of the NBG breeding indicate the possibility of their successful cultivation both in continental and maritime areas with a high level of humidity in the temperate zone and in the dry Mediterranean climate of the subtropical climate zone, which reveals their significant adaptive potential. Conclusions. Obtaining varieties of hybrid Clematis of domestic breeding is important for the implementation of sustainable horticulture practices on the territory of Ukraine, since a significant part of the modern introduced assortment of Clematis raises doubts about their adaptability to the local climate, and requires additional research into their adaptive potential. A successful combination in vertical landscaping of NBG­bred Clematis belonging to different varietal groups can ensure continuous flowering from May to the end of the season. These unique characteristics of Clematis ensure the creation of not only environmentally sustainable, but also visually appealing spaces that will contribute to the overall health and beauty of the urban environment.

A Comparative Analysis of Island vs. Mainland Arthropod Communities in Coastal Grasslands Belonging to Two Distinct Regions: São Miguel Island (Azores) and Mainland Portugal

Coastal grasslands host diverse arthropod communities and provide important ecosystem services. Islands, being isolated environments, are expected to have simpler ecosystems than continental areas, with the few successful colonizing species often attaining high densities; however, these patterns are still poorly documented for coastal grassland arthropods. We conducted a comparative study of the biodiversity of arthropod communities in two distinct coastal grassland ecosystems (Portugal mainland and the Azores) with the following objectives: (a) to investigate the arthropod community composition in both locations; (b) to compare the diversity profiles in both locations; (c) to investigate potential density compensation in the island’s arthropod communities. For four months, arthropods were collected on the Island of São Miguel, Setúbal Peninsula, and Sine’s region and subsequently classified into taxonomic groups. With the data collected, Hill Numbers were calculated for each region. We confirmed that the richness on the mainland was higher than in the Azores, and we found some apparent abundance compensation in the Azores. At the same time, we also observed that many species in the Azores are also present in the continental coastal grasslands of mainland Portugal.

Ghanaian Small and Medium-Scale Enterprises (SMEs') Readiness for African Continental Free Trade Area (AfCFTA) Implementation

This paper seeks to assess Ghanaian Small and Medium-Scale Enterprises (SMEs') readiness for the African Continental Free Trade Area (AfCFTA) Implementation. The research instrument used to collect data was questionnaires and the study employed descriptive research design. The study randomly selected 250 SMEs from a population of 480 SMEs that were registered members of the Ghana National Chamber of Commerce and Industry, Cape Coast Branch and operating within manufacturing, pharmaceutical, herbal, tourism, hospitality, food and beverage, agribusiness, garment, leather, and textiles. Data collected from the SMEs was analysed using SPSS, version 28. The findings from the study shows that, there is a significant gap between Ghanaian SMEs' readiness for AfCFTA implementation. The study finds out that although majority of SMEs are capable of innovation and developing new products, they also have limited knowledge of export documentation, trade information and infrastructure, trade finance, and funding for expansion. They also have low knowledge and lack a basic understanding of the benefits of AfCFTA, its advantages, components, protocols, and Rules of Origin. The study again revealed that the obstacles facing Ghanaian SMEs exportation are high cost of production, border delays, poor infrastructure, high inflation, difficulty in accessing credit, and language problems. Based on these findings, the study recommended that SMEs needs to be retooled particularly in the area of AfCFTA Rules of Origin, its objectives, components, and Ghana’s trade policy to improve their readiness for AfCFTA implementation. Again, businesses should concentrate more on value addition, and be dedicated to looking for ways to enhance their current or existing products to outperform comparable products from other African nations.

Implementing African Continental Free Trade Area: Lessons from Afro-Pessimists and Afro-Optimists

Global cooperation has been an acceptable strategy for addressing many of the world’s challenges. The African Continental Free Trade Area (AfCFTA) agreement which entered into force on 30 May 2019 was designed in a similar light for Africa’s development. Its objectives among others are to create a single market for goods, and services, and deepen the economic integration of the African continent by the vision of an integrated, prosperous, and peaceful Africa as enshrined in the Agenda 2063. However, these benefits may not be realized unless member states garner concerted and sustained efforts to ensure the effective implementation of the AfCFTA. These efforts often elude most developing countries, and it is against this backdrop that this study attempts to investigate whether the contrasting perspectives of the Afro-pessimists and Afro-optimists could be of relevance to AfCFTA implementation. Using desk review methodology, the study synthesized both empirical and theoretical literature and found that Afro-pessimists are very critical and paint a gloomy picture of Africa. Whereas the Afro-optimists, are more positive looking with the claim that Africa is mistreated and its achievements are inordinately ignored. Significantly, both perspectives deepen understanding of the strengths and weaknesses of Africa’s development, providing a useful context for either the failure or success of the AfCFTA’s implementation. The key lesson the study draws is for Africans to maximize their strengths as much as possible and minimize their weaknesses. This will actualize the “Africa rising” phrase and lead to the majority of Africans rising with Africa.

Regional trade agreements and economic integration in Africa: assessing the impact of the African Continental Free Trade Area (AFCFTA)

This article examines the impact of Regional Trade Agreements (RTAs) on economic integration in Africa, focusing on the African Continental Free Trade Area (AfCFTA). As the largest free trade area globally, AfCFTA aims to create a unified market for goods and services across 55 African Union member states, fostering economic growth, reducing trade barriers, and enhancing intra-African trade. This article assesses the potential economic benefits of AfCFTA, including increased market access, industrialization, and job creation. It also considers the challenges of implementation, such as infrastructure deficits, varying levels of economic development, and non-tariff barriers. Through case studies of key African economies, including South Africa, Nigeria, and Kenya, the article explores how AfCFTA is reshaping trade dynamics and regional cooperation. Furthermore, it evaluates the role of AfCFTA in addressing Africa’s dependence on external markets and enhancing global competitiveness. The article concludes by providing recommendations for policy reforms, capacity building, and regional cooperation needed to maximize the benefits of AfCFTA. By analyzing both opportunities and challenges, this article offers insights into how AfCFTA can drive deeper economic integration and sustainable development across the African continent.

Morocco, at the Heart of the Harmonization of the African Union's Migration Policies: Context, Complexity, Diversity, Effects and Challenges

Since the mid-1980s, the European Union has adopted a cautious attitude to migratory flows. It has constantly stepped up initiatives to combat immigration, by tightening border controls and reducing the granting of visas, thereby forcing would-be emigrants to look for alternatives. At the same time, Africa is facing unique migration challenges. The consequences of colonization, the imposition of capitalist relations and the development of an extroverted economy, among others, continue to influence current migration dynamics. Persistent economic crises, exacerbated by inequitable global economic policies, are driving many people to seek better opportunities elsewhere. In addition, the effects of climate change, such as desertification, droughts and floods, are intensifying migratory pressures. African countries therefore need to develop effective migration policies to govern migratory flows and respond to geopolitical challenges. It is crucial to put in place regional and international cooperation mechanisms to manage migration in a coordinated and humane manner. This means thinking carefully about migration issues, considering the historical, economic and political realities that shape them. This issue must be at the heart of the concerns of States and the African Union. It is true that attempts are being made at continental level, such as the Kampala Convention and the establishment of the African Continental Free Trade Area (ACFTA), but these measures can only be truly appreciated if they are applied on the ground.

Innovative approaches to enhancing logistics for adapting to the evolving demands of manufacturing companies in East Africa through improved lean strategies

This article explores innovative approaches to enhancing logistics for manufacturing companies in East Africa through improved lean strategies. The region faces numerous logistical challenges, including poor infrastructure, political instability, and supply chain disruptions. These issues are critical barriers to the competitiveness and growth of East African manufacturers in a globalized market. By adopting lean strategies such as Just-in-Time (JIT) inventory management, Value Stream Mapping (VSM), and Continuous Improvement (Kaizen), companies can streamline their operations, reduce costs, and improve customer satisfaction. The article highlights the importance of localizing lean practices to fit the unique context of East Africa, emphasizing the need for a cultural shift towards continuous improvement and innovation. Additionally, it underscores the role of advanced technologies, public-private partnerships, and regional collaborations in optimizing logistics systems. The future of logistics in East Africa is seen as promising, with opportunities arising from the African Continental Free Trade Area (AfCFTA) and the potential for technological advancements to reshape the logistics landscape. Ultimately, the article calls for concerted efforts from governments, businesses, and NGOs to invest in infrastructure, foster innovation, and promote sustainable logistics practices. By doing so, East African manufacturers can overcome current challenges and position themselves for long-term success in the global market.

Differential exposure to second-generation anticoagulant rodenticides in raptors from continental and insular regions of the Iberian Peninsula

The global impact of anticoagulant rodenticides (ARs) on non-target species is well-recognized. Birds of prey, as apex predators, are highly vulnerable to AR exposure and are widely used as biomonitors for priority pollutants in Europe. This study investigates differential SGAR exposure in raptors from insular versus continental regions, hypothesizing greater exposure in insular areas due to ecological factors like reduced prey diversity, intensive rodenticide use, and resistant rodent populations. We analyzed the livers of 190 common kestrels (Falco tinnunculus) and 104 common buzzards (Buteo buteo) across the Iberian Peninsula and its archipelagos using LC-MS/MS to assess their role as AR sentinels and the differences between insular and continental areas. Results revealed a high prevalence (>80%) of second-generation anticoagulant rodenticides (SGARs), with brodifacoum and bromadiolone, being the most frequent. Multiple SGAR detections were also common (≈50%). A binomial logistic regression showed that species and region significantly influence the likelihood of SGAR exposure. Kestrels had a greater probability of exceeding 100 ng/g wet weight (ww) compared to buzzards. Raptors from insular territories were ten times more likely to have higher SGAR concentrations than those from continental areas. However, the legal restriction on SGAR bait concentrations that came into effect in 2018 did not significantly impact exposure levels. This study highlights the need for targeted conservation efforts to mitigate AR exposure risk in vulnerable island ecosystems.

Breaking Down Barriers: Preparing Africa's Insurance Market for AfCFTA Success

This article examines the regulatory challenges that affect the readiness of the African insurance sector for expansion and integration under the African Continental Free Trade Area (AfCFTA) framework. Employing a mixed-methods research design, the study integrates qualitative interviews with senior industry executives and quantitative survey data from key stakeholders to identify and evaluate the primary regulatory barriers impeding market preparedness. The analysis reveals several critical obstacles, including regulatory fragmentation, inconsistent enforcement of standards, and inadequate cross-border coordination. The findings suggest that addressing these challenges is crucial for realizing the full potential of AfCFTA in the insurance sector. The article concludes by providing strategic recommendations aimed at fostering regulatory coherence, enhancing market readiness, and supporting sustainable growth across Africa’s insurance markets.

Sustainable development goals implementation in a post‐colonial African State: Any future for the African Continental Free Trade Area?

AbstractThis paper examined the prospect of the African Continental Free Trade Agreement in the context of the SDGs. It took its bearing from the contemporary structure of most African states, arguing that the reality of the continent's postcolonial condition could impede the implementation of the AfCFTA. Its refrain is that studies on how Nigeria and South Africa, as regional powers, have used their economic and political influence to advance the SDGs' implementation throughout Africa, using different South–South development frameworks are few. In other words, the institutionalization of a strategic collaboration agenda through a Nigeria‐South Africa‐coordinated African response to the new powers, in the area of timely implementation of the SDGs is lacking. This study affirms that for the AfCFTA to be successful, it is incumbent on the regional hegemons to build a suitable institutional framework and governance structure that upholds the rule of law and encourages harmonization, consistency, and predictability.

Embracing the African continental Free trade Area: Unpacking Malawi’s economy response to trade liberalization

The impact of trade liberalization on Malawi’s economy has been a hotly debated topic. To shed light on the subject, a study was conducted using the PEP-1–1 CGE model and the latest Malawi’s Social Accounting Matrix (SAM) from 2019. The results were eye-opening, revealing the potential effects of the African Continental Free Trade Area (AfCFTA) on various sectors of the economy. The removal of trade tariffs is predicted to have a significant impact on prices, with a decrease of 26.31% in the agricultural sector alone, services (−7.88%), public administration (−9.92%), and manufacturing and industry (−11.23%) imposing hopes of improving food affordability and food security. However, it is expected to have adverse impacts on wage rates in the agricultural sectors (−18.78%), manufacturing and construction (−19.01%), services (−2.79%) and public administration (−15.81%). Additionally, while exports are expected to increase, the country’s balance of payments may suffer as imports are likely to outweigh foreign earnings. This could also lead to a decrease in government revenue from taxes. To mitigate these effects, the study suggests implementing export restructuring strategies, particularly in industries like manufacturing and construction, and promoting diversification of local production to boost competitiveness and improve wage rates. With these measures in place, the government will not only offset potential losses but also tap into new sources of taxable income.

Regional (economic) integration, political stability uncertainty and (intra-African) exports

The economic literature reports ambiguous effects of regional economic integration (REI) and political stability on exports. Therefore, this research analyzes the effects of REI and political stability on intra-African exports, compares them to the effects on intra-African imports and explores the combined effect of REI and political stability on intra-African exports. We use the two-stage least squares and fixed-effects approach which includes the two-step feasible generalized method of moments (GMM) estimation to address endogeneity issues in a panel of 49 African countries over the period of 1996–2022. The results show that REI and political stability lead to an increase in intra-African exports. However, while REI results in an increase in intra-African imports, political stability results in a decrease; similar findings are highlighted for overall intra-African trade as well as for total exports of goods and services. The results remain robust across diverse estimation techniques. Furthermore, they reveal that political stability plays a role in amplifying the relationship between REI and intra-African exports. Supporting the African Continental Free Trade Area agenda, these findings imply that African policymakers need to (i) strengthen REI to increase intra-African trade and (ii) improve political stability to ensure that a greater part of REI is canalized in a more effective way in order to boost intra-African exports.

A Commentary on the Jurisdictional Challenges in the Rand- Dollar Exchange Manipulation "Cartel": Competition Commission of South Africa v Bank of America Merrill Lynch International Designated Activity Company [2023] ZACT 26 (30 March 2023)

Cartels are the most egregious of competition law transgressions, because they entail a concerted effort on the part of cartel members to deliberately distort the market through price fixing, bid rigging, market allocation and constraining the supply of goods and services. Despite efforts by national competition authorities in various countries to combat cartelism, cartels have proved to have long tentacles, often extending beyond borders and morphing into "cross-border cartels". This contribution discusses one of the major challenges that cross-border cartels poses to competition authorities, that of prosecutorial and penal jurisdiction. The note focusses on the "banking cartel" that has been and still is the subject of contentious litigation. In March 2023 the Competition Tribunal (the Tribunal) handed down judgment in the matter of the Competition Commission of South Africa v Bank of America Merrill Lynch International Designated Activity Company [2023] ZACT 26 (30 March 2023). There were several questions in the matter, including the jurisdiction of the South African competition authorities to investigate and prosecute firms not incorporated or operating in South Africa (pure peregrini). The Competition Commission (the Commission) had initiated proceedings in the Tribunal against a host of banks for alleged cartel conduct, and some of the respondent banks raised objections and exceptions relating to the jurisdiction of the South African competition authorities. The note observes that while national competition authorities may have prosecutorial jurisdiction against cross-border cartels, there is still a challenge in enforcing an order where cartels are non-resident in the country. The contribution also notes potential challenges to cartel enforcement on the African continent in light of the establishment of the African Continental Free Trade Area (AfCFTA). Due to the removal of various trade barriers, there is likely to be a rise in cross-border competition issues, including cross-border mergers and cross-border cartels. The note therefore discusses a pertinent issue, that of jurisdiction, which may well be a challenge within the AfCFTA.

Sino-Africa Relations Post-Covid-19: Issues for Consideration

Sino-Africa relations have been periodised into three phases. The first phase (1950s–1970s) includes the establishment of the People’s Republic of China (PRC) in 1949 and the decolonisation of African states. The second phase (1971–1990s) includes the drift of Sino-Soviet relations, the admission of China into the United Nations Security Council (UNSC), as well as the end of the Cold War. The third phase (2000s–2020) covers the inclusion of China into the World Trade Organisation (WTO) in 2001, as well as the establishment of the Forum on China-Africa Cooperation (FOCAC) in 2010. This article considers the fourth phase of Sino-Africa relations, argued to have begun in 2020 post-Covid-19, taking place at a time of de-globalisation, the ongoing Russia-Ukraine war and the US-China trade war. We assert that the latter changing global dynamics must be considered in making sense of Sino-Africa relations today. The article argues that despite such a changing global political order, there have been continuities and changes in China’s relations with the African continent. This is evident in the tightening of its relations with Africa, irrespective of ongoing dynamics in global affairs. Despite concerns about the USA’s reprioritisation of Africa, the establishment of the African Continental Free Trade Area (AfCFTA), China’s Belt and Road Initiative (BRI), vaccine diplomacy, and China and African States’ “neutrality” stance on various ongoing conflicts, it is safe to say that Sino-Africa relations will triumph even in this new phase.

Africa’s lingua franca and its role in the successful implementation of the AfCFTA: a case for Kiswahili as the African commerce and epistemological language

The African Continental Free Trade Area (AfCFTA) is the largest free trade agreement in the world in terms of its membership and it has tremendous potential to lift millions of Africans out of poverty through boosting intra-Africa trade by ensuring that Africa has one gigantic market of over 1.3 billion people. For this to be achieved, this trade agreement must be implemented rapidly and to the letter. This article therefore argues that, among others, the use and adoption of an African indigenous language such as Kiswahili can play an important role in enabling Africans to trade with one another with ease and mutual trust. The adoption and use of this language as a potential lingua franca for commerce and teaching and learning also has the potential to harness the innovation and creativity of Africans as this would be emanating from the age-old ingenuity of our forebears. The main argument made here is that language is both the reservoir and vessel for culture and indigenous knowledge systems (IKS), and without its maximum exploitation, our societies will not industrialise and develop. Methodologically, qualitative semi-open-ended interviews and non-participant observation were conducted in Kenya, Tanzania and South Africa to gauge experts’ views on the utility of Kiswahili as a potential Pan-African language. Pan-Africanism and Afrocentricity are key theories deployed in giving shape to this study.

Foreign Investment in Fragile and Conflict-Affected Situations: Opportunities, Challenges and Prospects

African countries remain stubbornly plagued by fragility and conflict-affected conditions. Out of thirty-seven countries categorized as fragile and conflict-affected states, African countries are nineteen in number representing about 51% of the total states. The remaining African countries that are excluded in this list do not fare better in institutional and social fragility index, nor are they delivering enduring peace and sustainable development to their populace. The African Union (AU)’s approval of the Phase II of the African Continental Free Trade Area Agreement (AfCFTA) constitutes a pragmatic approach to use investment framework to change the climate of fragility and conflict. Foreign investment presents a veritable opportunity to turn the fragile and conflict-affected African states into a hub of peace and development. The increase in international investment brings with it the spillover of skills, know-how and technology into the host state. Additionally, foreign investment increases employment and revenue generation, diversification and improvement in the quality of products and services, and overall improvement in the standard of living. Equitable and inclusive sharing of revenues from natural resources similarly promotes societal cohesion and limits the triggers of institutional fragility. Consequently, this paper seeks to explore the modalities for the use of foreign investment as a pathway to inclusive development in African countries plagued by fragility and conflict.

Composite Melt–Rock Interactions in the Lowermost Continental Crust: Insights from a Dunite–Pyroxenite–Gabbronorite Association of the Mafic Complex from the Ivrea–Verbano Zone (Italian Alps)

Abstract The processes leading to the building of the continental crust through magmatic underplating are fundamentally unknown, mainly because of the rare accessibility to deep level sections of the continental crust. The Italian Alps expose the Permian Mafic Complex, an 8-km-thick gabbronorite–diorite batholith that intruded the lower continental crust during the post-Variscan transtensional tectonics. We present here a petrological and geochemical study of a concentric dunite–pyroxenite–gabbronorite association, called Monte Mazzucco sequence, enclosed at deep levels of the Mafic Complex, thereby allowing us to provide new insights into the magmatic processes driven by emplacement of mantle melts in deep crustal continental areas. The studied sequence includes a ~ 60-m-thick dunite lens, in which olivine (82 mol % forsterite) is associated with accessory Cr-spinel including blebs and lamellae made up of magnetite. The dunite lens is permeated by mm- to cm-scale thick magmatic veins, which range in composition from hornblende lherzolite to olivine hornblendite and hornblende websterite. The lens is mantled by a m-scale ring consisting of amphibole-bearing (≤1 vol %) websterite, and the websterite ring is in turn enclosed by amphibole-free gabbronorites. Both magmatic veins within the dunites and mantling websterites typically include an oxide association of Al-spinel and magnetite. Remarkably, the hornblende websterite veins and the mantling websterites are typically plagioclase-free and include clinopyroxene and amphibole with chondrite-normalized rare earth element patterns characterized by negative Eu anomaly. The mantling websterites display a subtle, gradual outward decrease of Mg# for orthopyroxene, clinopyroxene and accessory olivine, coupled with an increase of the negative Eu anomaly in clinopyroxene and amphibole. The enclosing gabbronorites are amphibole-free and have a chemically evolved signature. We propose a petrogenetic scenario including two major events of melt–dunite interaction. The first resulted from focused reactive melt infiltration and formed the magmatic veins within dunites. The hornblende lherzolite and the olivine hornblendite veins were produced by focused reactive melt migration through dunite grain boundaries, involving dissolution of olivine and recrystallization of Cr-spinel into Al-spinel and magnetite, whereas the hornblende websterite veins crystallized from melts penetrating through narrow fractures and recording earlier plagioclase fractionation. Most likely, the infiltrating melts were overall derived from an evolving H2O-rich magma emplaced below the dunite body. The second event of melt–dunite reactive interaction developed the websterite ring around dunites. We envision that the outermost domain of the dunite body was replaced by websterites in response to reaction with an invading H2O-poor melt, which had previously undergone plagioclase fractionation. The dunite replacement occurred under dynamic conditions, which promoted the reaction progress, thereby leading to total or almost total dissolution of precursor olivine, and started to form the lens shape of the Monte Mazzucco ultramafic association. The gabbronorites closely adjacent to the websterite ring represent the crystallization products of the invading melt.
