Cartografia morfogenética do Chapadão do Diamante na Serra da Canastra

Abstract

The central problem of this research lies in the tension between the increasing automation of geomorphological mapping and the need to preserve the interpretative component inherent in the genetic approach to relief. Added to this is the scarcity of studies that prioritize morphogenetic mapping as a central element of research, especially in areas of high geomorphological complexity. This gap hinders the advancement of integrated approaches that reconcile technical rigor and an evolutionary reading of the landscape. In view of this problem, the dissertation aims to develop a morphogenetic map of Chapadão do Diamante, on a scale of 1:20,000, structured in four hierarchical levels, with theoretical and methodological foundations in Ab'Saber (1969), Ross (1992), Bashenina et al. and Nazar and Rodrigues (2019). The methodology was based on the articulation between classical geomorphological analysis procedures and the use of geotechnologies, prioritizing the relationship between landforms, morphogenetic processes, and surface materials. As a result, the morphogenetic map developed became an instrument for the synthesis and integrated interpretation of the landscape, allowing for the individualized and joint analysis of genetic systems, relief models, and associated features. The mapping enabled the identification of five major genetic systems in the ChD: Bioturbation System, Denudation System, Structural System, Mixed System (Structural/Denudation) and the Fluvial System, highlighting the coexistence and overlap of structural, denudational, biogenic, and fluvial processes, acting at different spatial and temporal scales, strongly conditioned by the quartzite geological framework, current surface dynamics, and anthropic interventions, which, in certain contexts, contribute to the intensification of erosive processes.
