SYRMEP beamline: state of the art, upgrades and future prospects

SYRMEP is the hard X-ray imaging beamline of Elettra synchrotron offering X-ray full-field techniques, micro-computed tomography (microCT) and phase-contrast modality in the energy range 10–40 keV. The beamline operates in a multidisciplinary research context spanning from biomedical applications to botany, from zoology to food technology and cultural heritage, from materials engineering to geology and earth science. Thanks to the flexibility of SYRMEP setup, in situ experiments can be performed as well, novel imaging methods can be developed and implemented in a synergical manner with interested users and collaborators. SYRMEP peculiar wide beam together with the long sample-to-detector distance enables multiscale phase-contrast studies with optimized contrast and spatial resolution on rather large specimens, such as human lung phantoms. This is particularly relevant in view of future clinical lung imaging foreseen in the framework of Elettra 2.0 program. Here, the current beamline features and recent upgrades are illustrated, an overview of the imaging methods routinely offered to SYRMEP users’ community is presented, and the outlook for the new beamline SYRMEP-Life Science (SYRMEP-LS) is reported.

A depth graph attention-based multi-channel transfer learning network for fluid classification from logging data

Fluid classification is a fundamental task in the field of geological sciences to achieve effective reservoir characterization and hydrocarbon exploration. Traditional fluid classification methods are often limited by long processing times and an inability to capture complex relationships within the data. To address this issue, this paper proposes a novel deep learning approach—the Deep Graph Attention Multi-channel Transfer Learning Network (DGMT), aimed at improving the efficiency and accuracy of fluid classification from logging data. This model comprises three key components: a graph attention layer, a multi-channel feature extractor, and a transfer learning module. The graph attention layer is designed to handle spatial dependencies between different logging channels, enhancing classification accuracy by focusing on critical features. The multi-channel feature extractor integrates information from various data sources, ensuring comprehensive utilization of the rich information in logging data. The transfer learning module allows the model to transfer knowledge from pre-trained models of similar tasks, accelerating the training process and significantly improving the model's generalization ability and robustness. This feature enables the DGMT model to adapt to different geological environments and logging conditions, showing superior performance over traditional methods. To validate the effectiveness of the DGMT model, we conducted experiments on actual logging datasets containing multiple oil wells. The experimental results indicate that, compared to common machine learning algorithms and other deep learning methods, the DGMT model significantly improves in accuracy and other classification performance metrics.

ORIENTAÇÃO ESPACIAL NO LEITO DO RIO JAGUARIBE – ITAIÇABA – CE

One of the ways of observing celestial stars aims to orientate in space, based on the cardinal points. In fieldwork in Geology, Geography, Cartography and related sciences, this observation helps to determine the directions and directions of the segments N-S (North/South) and L-W (East/West), through the visualization of the setting or rising of the Sun. This teaching, including illustration, is widely disseminated in textbooks from Elementary School, through High School and extending into Higher Education in the courses mentioned above.

The Global Humanization Event (GHE)

The recent rejection of the “Anthropocene Series/Epoch,” as proposed by the Anthropocene Working Group (AWG), by the International Commission on Stratigraphy (ICS) and the International Union of Geological Sciences (IUGS), has reopened discussion about the Anthropocene as a geological event. This event has been referred to as the “Anthropocene Event” (AE) or the “Anthropogenic Modification Episode” (AME). This essay briefly discusses these terms and concepts, and proposed to use new terms such as “Earth System Humanization Event” (ESHE) or “Global Humanization Event” (GHE), which are more specific and terminologically more consistent with the already defined geological events.

“Geological Wonders of Italy”: The Coveted Privilege of Disseminating Geology and Geomorphology through Science Documentaries in the Marche Region

This paper proposes an unusual method for the dissemination of geological sciences and the promotion of geotourism: a scientific documentary, where a representative itinerary of geological and geomorphological evolution of the Umbria and Marche regions was presented. The considerations that led to the identification of the geological route proposed to the editorial staff of FOCUS TV are presented in detail. At each stop, there was an explanation by academic professors and researchers, mainly from the Geology Division of the University of Camerino (MC), who explained the outcrops in detail. During the episode, insights were also given into the anthropogenic frequentation of the epigean caves in Frasassi (AN), ancient places of frequentation and worship thanks to their suggestiveness and the sense of magnificence that they can elicit. In addition to the illustration of the individual stops, the article offers further insights into the geomorphology of the most important geosites depicted, all of which are in natural parks or protected areas and characterized by a high landscape value. The result was the production of an episode of the television program ‘Geological Wonders of Italy: the Marche and Umbria Regions’, which was broadcast in October 2022 by the Italian national Mediaset group.

Multimodal analysis of renal stones to explore new biomarkers of urolithiasis

Despite advances in minimally invasive surgery, urolithiasis still recurs within the first five years after the first episode in more than 50% of patients. Researchers continue to search for new crystallisation inhibitors, metaphylaxis strategies and laser sources for stone destruction. Therefore, to achieve these goals, it is necessary to study kidney stones not only as the result of an isolated process of pathological biomineralisation in the human body, but also as a biogenic mineral or rock that obeys universal patterns and has certain properties. Consequently, kidney stones need to be studied using methods that are widely used in the geological sciences for the study of minerals, such as computed microtomography and petrological analysis. In this review, the properties of kidney stones studied using various research methods used in geosciences are discussed. These properties are also considered as new biomarkers of urolithiasis. This review discusses how new data from multimodal stone analysis can be used to develop personalised metaphylaxis and treatment strategies for all types of urolithiasis, including the most common idiopathic calcium-oxalate urolithiasis.

Mechanisms of Crustal-Mantle Material and Energy Exchanges: Impacts on Hydrocarbon and Geothermal Resources.

The exchange of matter and energy between crust and mantle significantly influences the formation and development of oil, gas, and geothermal resources. Understanding how these exchanges impact these resources is crucial in geological science. In many oil-rich basins in China, significant accumulations of H2, CO2, geothermal energy, and other associated resources linked to deep mantle materials or geological processes have been discovered. Therefore, investigating the effects of crust-mantle material and energy exchanges on these resources is of utmost importance. This paper aims to systematically analyze the effects of mantle materials (e.g., H2, CO2, catalytic elements) and energy upwelling into basins. It synthesizes the impacts of various organic-inorganic interactions on hydrocarbon generation, evolution of organic source rocks, reservoir development, and the formation and accumulation of oil and gas. Finally, it proposes a mechanism detailing how interactions between mantle matter and energy influence specific resources. Simultaneously, this study employs numerical simulations to uncover the specific impact of magma intrusions on the geothermal field of surrounding rock formations. It demonstrates that magma chambers, continuously supplied with mantle energy, create regional thermal anomalies and facilitate the development of high-temperature geothermal resources. This underscores that mantle materials and energy not only significantly influence the generation of oil and gas but also govern the formation of geothermal resources and the evolution of thermal reservoirs. This research provides a theoretical foundation for understanding the subsequent formation of oil and gas resources under the influence of deep geological processes. Moreover, it furnishes a scientific basis for evaluating and exploring the symbiotic relationship between oil and gas resources and geothermal reservoirs.

Ecocriticism

Abstract Over the last two decades, the Anthropocene and its calamitous signatures of climate upheaval, species loss, and biocultural fragmentation has garnered dedicated attention from ecocritics, ecologists, and the public. As the culmination of a fifteen-year scientific process, however, in early 2024, the International Union of Geological Sciences, or IUGS, rejected the Anthropocene as a unit of geological time in favour of a view of the Anthropocene as a temporally transgressive event. Prominent within the year’s work are trajectories in empirical ecocriticism, ecocritical ageing studies, intermedial ecocriticism, and blue ecocriticism, all of which place emphasis on agency, narrativity, and temporality. As the example of the blue humanities reveals, explored in this essay’s conclusion, intersections between ecocriticism and emerging areas of the environmental humanities continue to generate novel directions. The expansion of interdisciplinary research engaging ecocritics, social scientists, ecologists, and geoscientists is a potential outcome of the IUGS decision. As ecocriticism evolves in the era of the Anthropocene as an event, concerns of more-than-human agency, expression, and creativity will likely attract greater focus. In addition to presenting a broad overview of publications, each of the sections below hones in on one specific work. This review of ecocritical publications in 2023 comprises six sections: 1. Introduction: The Anthropocene from Epoch to Event, which contextualizes the IUGS’s refusal to ratify the Anthropocene as an official geochronological designation; 2. Ecocritical Directions: Towards More-than-Human Agencies, which focuses on the special issue of the journal Anthropocenes, ‘Life Out of Place’; 3. Empirical Ecocriticism: Appraising Environmental Narratives, which considers the landmark edited collection Empirical Ecocriticism; 4. Ecocritical Ageing Studies: Rethinking Narratives of Decline, which turns to the edited collection Aging Studies and Ecocriticism; 5. Intermedial Ecocriticism: Diversifying Anthropocene Narratives, evaluating Jørgen Bruhn and Niklas Salmose’s monograph Intermedial Ecocriticism; and 6. Conclusion: Ecocritical Agency and the Environmental Humanities, which reflects on developments in the blue humanities.

“Flipping” a Course: Is It Worth It? A Multiyear Analysis of Interactive and Student-Centered Pedagogy in an Introductory Physical Geology Course

The IGCP 714 Project “3GEO – Geoclimbing & Geotrekking in Geoparks” – Selection of Geodiversity Sites Equipped for Climbing for Combining Outdoor and Multimedia Activities

The IGCP 714 project “3GEO – Geoclimbing & Geotrekking in Geoparks” is financed by the International Geoscience Programme (IGCP) and supported by the International Union of Geological Sciences (IUGS). In this paper, we report on the results of the first phase of the project focused on the criteria to be adopted to select geodiversity sites equipped for climbing or trekking. The selection of geoclimbing sites and geotrekking routes is aimed at combining multimedia tools and outdoor activities for Geosciences promotion and conservation in UNESCO Global Geoparks, aspiring geoparks or geoparks project, and also in protected areas featuring geoheritage sites. Indeed, both outdoor activities and multimedia tools favour the pursuing of many of the United Nations Sustainable Development Goals (e.g., 3, 4, 8, 11). An international consortium of geoscientists from 12 different countries selected, through the proposed procedure, 22 geoclimbing sites, and then they also detected 30 geotrekking routes mirroring Earth geodiversity. At some test sites (geoclimbing and geotrekking) multimedia tools and digital outcrop models have been developed through different methodological approaches (e.g., Structure from Motion and Multi-View Stereo photogrammetry), to open the way to the second part of the project still in progress. These sites and the relative virtual models are herein also shown. The final aim of the IGCP 714 project is indeed to create an open data repository (digital outcrop models, videos, virtual tours, photos, scientific information, and interpretations) to upload data of the selected sites to mirror Earth geodiversity for different users including tourists and school groups.

Development of Certified Reference Materials Set for Open Porosity of Mammoth Ivory

Mammoth ivory is in demand in the jewelry industry, folk crafts and in the manufacture of cosmetics. This unique natural resource is an alternative to the prohibited extraction of ivory. It is fundamentally important for consumers to identify the raw material unambiguously as mammoth ivory and to accurately determine the grade of the material.The article presents the results of a study, which resulted in the development of a reference materials set of open porosity of the mammoth ivory. The reference materials are cylinders with an outer diameter of 30 mm and a height of 30 mm. Certified values of open porosity were determined by gas pycnometry. Reference materials are intended for certification of measurement methods and control of the accuracy of measurement results of open porosity of mammoth ivory in laboratory conditions. Reference materials can be used for various types of metrological control if the metrological characteristics of reference materials correspond to the established requirements.The research materials are of an applied nature for a number of economic sectors where mammoth ivory is used as a raw material. Reference materials of mammoth ivory are in demand in materials science, biology, geology, and other natural sciences, and in expert activities to determine the authenticity of products made from mammoth ivory. The article may also be of interest to students and teachers of natural sciences in higher education, as well as anyone interested in artifacts of ancient fauna.

The Anthropocene Is More Than a Time Interval

AbstractFollowing the recent rejection of a formal Anthropocene series/epoch by the Subcommission on Quaternary Stratigraphy (SQS) of the International Commission on Stratigraphy (ICS), and its subsequent confirmation by the International Union of Geological Sciences (IUGS), the opportunity arises to reset the definition of the Anthropocene. The case for informally recognizing the Anthropocene to be a major planetary event of Earth system transformation offers a promising way forward, but this has been criticized by proponents of an Anthropocene series/epoch. In order to move on from the assumption that it must be a time interval, and to foster a more transdisciplinary and inclusive approach, the main points of the critique must be directly addressed.

Výuka geověd včera, dnes a zítra – reflexe učitelů a žáků

This article focuses on the historical development, current state, and future perspectives of geology education in the Czech Republic. The theoretical part of the article presents analysis of the evolution of the geology curriculum and its position within the Czech educational system. It highlights significant personalities and events in geological sciences and describes the changes in geology education since the 18th century to the present. The empirical part of the article employs qualitative research through focus group interviews to reflect on current approaches to geology education in lower secondary schools (ISCED 2). The respondents included ninth-grade students from primary schools, teacher education students at the Faculty of Science of Charles University, and science teachers. Based on their statements, SWOT analyses were created to identify the strengths, weaknesses, opportunities, and threats associated with geology education. Strengths include practical field exercises and field trips that provide students a direct contact with geological materials and demonstrate interdisciplinary connections between geology, chemistry, physics, and geography. Weaknesses involve low student interest, lack of teaching aids, and the complexity of integrating geology into other subjects. Threats include low teacher motivation and inadequate resources in school natural science collections, while opportunities lie in tandem teaching and collaboration with research and educational institutions. The article emphasizes the need to strengthen interdisciplinary connections, increase teacher support and motivation through further education, and improve school collection. Emphasis is also placed on popularizing geology to make it more attractive not only to students but also to the broader public. Overall, it is essential for geology education to respond to current challenges and trends, thus contributing to the formation of comprehensive scientific education that will inspire students to further study and interest in natural sciences.

Dating the Dawn of the Anthropocene

Abstract This article provides indepth insight into the debate (based on stratigraphic findings) as to the exact date that Earth entered the Anthropocene Epoch. Generally, in Human and Social Sciences, the date of the boundary is paid less attention than the systemic shifts resulting from it. (There have been a number of publications on our surpassing of the planet’s limits, and passing of the point of no return.) However, it is important to understand this debate based on stratigraphic data, because sooner or later, the International Union of Geological Sciences will amend the geological timescale to include the Anthropocene – even if, to date, the process of formal definition has been interrupted by the negative vote on 5 March 2024 of the Subcommission on Quaternary Stratigraphy (SQS) of the International Commission on Stratigraphy (ICS) after a positive vote in 2023 by the Anthropocene Working Group (AWG) proposing to date the onset of the Anthropocene in 1950 (with a “golden nail” in the Crawford lake beds). In future, almost all the world’s students will learn the date when we entered it. This article explores each of the possible dates when stratigraphic data suggest the Anthropocene may have started. This should hand tomorrow’s teachers the keys to understand what may sometimes seem an obscure expert debate.

“Received no awards”: from the pages of the biography of a repressed scientist, G. L. Stadnikov (1880–1973)

Georgy Leontievich Stadnikov (also spelled Stadnikoff and Stadnikow) (1880–1973) was a Russian / Soviet organic chemist, the author of fundamental works in the field of chemistry of fossil fuels, well-known in Russia and abroad. In 1957, he was nominated for the Nobel Prize in Chemistry. In the Soviet era, he was twice subjected to repressions. In 1939–1955, he served in forced labor camps of the Komi Autonomous Soviet Socialist Republic. Based on the publications about Stadnikov, his scientific works, and the memoirs of geological scientists B. L. Afanasyev and L. N. Belyakov, discovered by the author in the collections of the K. G. Voinovsky-Krieger Geological Museum (Vorkuta), Stadnikov’s scientific biography is reconstructed. Georgy Leontievich was a pupil of V. V. Markovnikov and N. D. Zelinsky, the founders of the foremost Russian school of organic chemistry. He conducted research in the field of origin and genetic classification of fossil fuels. During his incarceration, Stadnikov continued with his research work. At the labor camps located in the European North-East of the USSR, he tackled the problems arising in the course of commercial development of coal deposits in the Pechora coal basin. Stadnikov’s research had an important role in the development of fossil fuel chemistry and his work in the harsh conditions of the Arctic facilitated the coal industry formation in the Komi Republic.

A bluestone boulder at Stonehenge: implications for the glacial transport theory

Abstract. There has been considerable dispute over the mode of transport of the Stonehenge bluestones from their multiple sources in West Wales. For a century most archaeologists have accepted that the stones were transported by humans, but a number of earth scientists have taken the view that they were entrained and transported to Salisbury Plain by glacier ice. There is remarkably little evidence in support of either theory, and for this reason any new description of a possible glacial clast found at or near the stone monument is of potentially great importance. A small bullet-shaped boulder of welded tuff was found in a Stonehenge excavation in 1924, and apart from a brief examination by geologists from the Institute of Geological Sciences (IGS) around 1970, it has been stored out of sight and out of mind. Its geological source is uncertain. Following a detailed examination of its shape and surface characteristics it is now proposed that it has been subjected to glacial transport and that it has had a long and complex history. It is also proposed that the abundant weathered and abraded bluestone boulders and slabs at Stonehenge were also glacially transported, along with many of the cobbles and stone fragments found in the sediments of the local landscape. The elaborate archaeological narrative of bluestone quarrying and human transport to Stonehenge must now be re-examined.

The geological footprint of plastics

The significant impact of plastics on Earth's environments has transformed from being a symbol of modern innovation to a major ecological concern. This perspective paper explores the integration of plastics into geological contexts, emphasizing their role in contemporary sedimentary processes. It examines the lifecycle of plastics, from production to disposal, and their subsequent interaction with natural sedimentary cycles. The production and usage of plastics have led to considerable environmental repercussions. One of these, is their incorporation into geological systems and the formation of novel geological materials. Such a phenomenon challenges traditional geological concepts and necessitates a multidisciplinary approach encompassing geology, chemistry, and environmental science.
