Interpretación de marcadores geomorfológicos planares y lineales para la identificación de tectónica activa en la zona de Yamana - Catacocha.

Abstract

Abstract: In the present research project, the identification of active tectonics in the Yamana parish of the Paltas canton was made, from the interpretation of planar and linear geomorphological markers such as alluvial fans, terraces, current channels, among others and their corroboration through the application of three geomorphological indexs: gradient of the channel, sinuosity of the mountainous front and relation width/height of the valley, with the purpose of obtaining information of the neotectonic activity of this sector. The general aim of the study is to relate the tectonic structures with the existing landscape and lithology, for this it was necessary the simultaneous work of office and field progressively developed in several stages, starting from the bibliographic and cartographic compilation, data processing, elaboration of maps and the analysis of the results; contributing with new information that serves as base for future research. The results show that in the study area most of the geomorphological features indicating neotectonic activity are associated with the Río Playas fault system and distributed along its main fault structures: Yamana and Rio Playas.
