Geoecological profile of the Serra do Gandarela National Park, Minas Gerais, Brazil
(2021-02-02) dos Santos, Darcy José; de Azevedo Ruchkys, Úrsula; Panisset Travassos, Luiz Eduardo
This paper presents a geosystemic study of the Serra do Gandarela National Park. This conservation unit is inserted in the context of the Quadrilátero Ferrífero, in Minas Gerais, where outcrops of Precambrian lithostratigraphic units of the Rio das Velhas and Minas Supergroups can be found. Thus, a geoecological profile was elaborated using a methodology of cartographic representation of a transect on the area of interest. This favours the elaboration of horizontal readings along with each represented element, as well as vertical readings, where correlations can be interpreted between the various elements present. The compartments of the morphostructural domains elaborated for the Belo Horizonte Southern Metropolitan Region Environmental Protection Area Project (Projeto APA Sul da Região Metropolitana de Belo Horizonte) were used as units of analysis for interpretation of the geoecological profile. The constructed geoecological profile enabled a more holistic understanding of the study area, which may contribute to the management of this conservation unit.

The Educational Potential of Geodiversity in Ferruginous Geosystem: the Example of the Quadrilátero Ferrífero, Minas Gerais, Brazil
(2021-03-28) José dos Santos, Darcy; Ruchkys, Úrsula; Eduardo Panisset Travassos, Luiz
One of the most significant ferruginous geosystems in Brazil and worldwide is the Quadrilátero Ferrífero, located in Minas Gerais, in its southeastern part. Its economic importance imposes intense pressure on unique environmental attributes, such as rare species of flora and fauna, speleological sites, scenic beauty, water resources, geological outcrops and fossils. To protect one of the few remnants of this geosystem not yet economically used by mining, a conservation unit of integral protection was created in 2014: the Serra do Gandarela National Park. In this context, the article aims to inventory and evaluate representative sites of geodiversity for educational purposes, indicating a methodological procedure that can be used for other ferruginous geosystems in Brazil and the world. For this, two methodological steps were used. The first involved assessing the study area as a whole, using map algebra which considered geodiversity, environmental vulnerability and capillarity of access roads. Using the results of the previous one, the second stage evaluated six specific geodiversity sites in the study area for didactic use, from a qualitative, quantitative point of view and regarding the risk of degradation. The results show that this integrated evaluation proved to be suitable, allowing the identification of the potentialities and risks of the selected sites and understanding the implications for the educational use of each one of them due to their location within the conservation unit.
