Morphostructural analysis of das Cinzas river hydrographic basin (SP): Ribeirão do Pinhal and Santo Antônio da Platina topographic charts

Abstract

This project is part of a larger project toward a better understanding of sedimentation, morphogenesis, and Cenozoic tectonics of the das Cinzas river hydrographic basin, northern Paraná. The objectives consist of outlining the morphostructural framework of the area covered by the IBGE topographic sheets "Santo Antonio da Platina" and "Ribeirão do Pinhal" on a scale of 1:50.000 (sheets SF 22-ZC-II-4/MI-2760-4 and SF 22-ZC-II-3/MI-2760-3 SF) into the context of the das Cinzas river hydrographic basin, and Paraná Basin in terms of geological/geomorphological context, in order to identify and distinguish the geomorphologic features accommodated from passive pre-existing geological structures. The study involves a multidisciplinary approach in which geological and geomorphological methods and techniques will be used with an emphasis on morphostructural characterization of the area. A systematic analysis of processes occurring during the Cenozoic is of utmost importance for understanding the current geomorphologic dynamics, as the successive phenomena contributed significantly to the sculpture of the landscape today.
