Caracterización morfoestructural del frente de fallamiento Catamayo - La Picota.

Abstract

Abstract: The main objective of the research work was to characterize the structures (faults) and their associated tectonic morphologies of "Catamayo - La Picota" fault, using indirect indicators as morphological surveys, which allowed the identification of faults, and tectonic morphostructures. And morphometric indexes such as elongation of the basin, gradient and sinuosity of the mountainous front. The direct indicators were the kinematic microstructures of faults, where approximately 60 of these microstructures were described and measured along the fault, from Gonzabal to El Tambo, for kinematic characterization of the segments and identify their geometry. The segments investigated corresponded to a system of transpresional faulting, where the morphology corresponded to predominant movement, presenting different geometries (steps, anastomosed, positive horse tails, among others). The resulting maps obtained were: maps of tectonic structures, a map of segmentation, maps of morphstructures of the fault, thematic maps of morphometric indexes "gradient-elongation" and "sinuosity"
