GEOESPELEOLOGIA E PRINCIPAIS ASPECTOS ESPELEOGENÉTICOS DAS GRUTAS BAIXADA DAS CRIOULAS I E II, ITAMBÉ DO MATO DENTRO, MINAS GERAIS

Résumé

This research presents the results of the geospeleological characterization of the caves Gruta Baixada das Crioulas I and II, as well as the main speleogenetic aspects associated to this karst system developed in quartzite rocks. There are still controversies about the denomination of features developed in non-carbonate rocks that present similarities with those developed in karstic relief. Among these features, those developed in quartzite rocks can be highlighted. Eleven caves formed in quartzite rocks were found in a mountainous location in the municipality of Itambé do Mato Dentro, the eastern border of Serra do Espinhaço Meridional, Minas Gerais State. They were studied with the objective to understand the inherent processes involved in their formation and development. The caves Gruta Baixada das Crioulas I and Gruta Baixada das Crioulas II form a karst system with important morphological, lithological, structural and endokarst deposits that are characteristic of karstic forms. That is the case of the Gruta Baixada das Crioulas I which is outstanding because of its morphometric attributes with a length of more than 1000m and a depth of approximately 75m. These measures are fairly representative when compared to other caves in quartzite located not only in Minas Gerais but also in Brazil.
