Mapeamento geomorfológico do Carste de Montes Claros - Brasil

Abstract

We seek to investigate the geomorphological characteristics of the karst region around Montes Claros, located in the north of the state of Minas Gerais, Brazil. The research is supported by the morphostructural analysis and the identification of the main forms of the karst relief, especially the exokarst. Digital processing and interpretation of orbital images, production of cartographic material in a GIS environment, field work and aerial images produced by drones were used. The final product is a semi-detail basic map with the geomorphological representation of this karst, at a scale of 1:50,000. In the research area, some hundreds of dolines and caves, dozens of sinkholes and upwellings, among other karst features such as uvalas, humes, blind valleys and lapies fields were mapped, which resulted in the distinction of a geomorphological unit which we call the Karst of Montes Claros.
