Abstract
The scientific knowledge of geological sites is a model to recognize the scores of stablish geoconservation and education/touristic proposes sites in geoparks territories. The alkaline massif of Pocos de Caldas is a structure of igneous alkaline origin (with volcanic and hypabissal deposits), formed, roughly, by breccias and tufts, effusive and hypabissal rocks and plutonic rocks. The purpose of this article is to recognize the international scientific relevance of geological sites in the Alkaline Massif of Pocos de Caldas (Minas Gerais State) as a requirement to be a UNESCO Global Geopark. Pocos de Caldas is located in the Southern region of Brazil and were know in the literature as the second biggest alkaline massif in the globe. We did a scientific database review in Scopus and manual review to recognize a science base for the issue of International publications of Pocos de Caldas. The publication of bibliographic stuffs mentioned in the text formed a database for knowledge of international sites and its relevance. The themes of volcanism, hydrogeology, geomorphology, rare minerals and samples are contextualizing the geossites arranged in the article. The significance of largest igneous alkaline massif in the globe, rare minerals founded in Pocos de Caldas, the uranium thematic in Brazil, the International Earth Science Olympiad and the hydrogeology are the main international relevant geossits in the region studied.

The purpose of this article is to recognize the international scientific relevance of geological sites in the Alkaline Massif of Poços de Caldas (Minas Gerais State) as a requirement to be a UNESCO Global Geopark
The distribution of geosites related to the organization of the geographic space presents the places of relevant geological interest, seeking to relate the outcrops that: a) contained greater international scientific representation; b) had an international scientific reference; and c) revealed the geological history of MAPC
It has a disassembly, too, for the security of these natural limits in relation to agribusiness, which modifies and makes all legislation responsible, including reproducing in other states of the nation. This is a problem in the Brazilian case, starting with the impact it has on territories and geopark projects, it is clear that it deals with the concession, but it is a concession for some years, so how does the utility tourism market work in the view of the State (?)
Summary
The purpose of this article is to recognize the international scientific relevance of geological sites in the Alkaline Massif of Poços de Caldas (Minas Gerais State) as a requirement to be a UNESCO Global Geopark. MAPC is a structure of igneous alkaline origin (with volcanic and hypabissal deposits), formed, roughly, by breccias and tufts, effusive and hypabissal rocks and plutonic rocks [18]. The geological issue of the proposed area for geopark, involves in a small scale, the South American lithospheric plate, comprises a sequence of localized volcanic events, represented by alkaline rocks that form stocks, plugs, possible chimneys, dikes and exceptionally spills and pyroclastics – known as the Alignment of Alkaline Rocks Poços de Caldas-Cabo Frio [41, 32]
