Caracterización geoquímica y mineralógica de sedimentos pesados y rocas en las microcuencas Guineo y Chirimoyo en el sector Puyango

Abstract

Abstract: This research was in the basins Chirimoyo and Guineo, there are in the forest petrified of Puyango canton, Loja province. This thesis describe the geochemical prospection of radioactive minerals, there will be minerals economic interesting, this description was possible because we described the lithogeochemical and active sediments survey in the principal drainages and interesting outcrops. The analysis realized in these samples of rocks and sediments were X Ray Fluorescence (FRX), and X Ray Diffraction With the results obtained it was possible to verify that there are geochemical anomalies of vanadium (5300 ppm in the rocks and 1400 ppm in sediments of the Chirimoyo micro basin), uranium (110 ppm in the rocks and 74 ppm in sediments of the Chirimoyo micro basin) and tin (6200 ppm in the rocks and 3500 ppm in sediments of the Guineo micro basin), since high concentrations were detected compared with the Clarke of concentration together with other elements that are pathfinder of uranium like Se, Mo, Cd, Ni, As, Pb. And minerals containing uranium and vanadium like carnotite and tyuyamunite.
