Estudio quimioestratigráfico en el sector Chicaña con fines prospectivos, parte 1

Abstract

Abstract: This Curricular Integration Work focuses on a chemostratigraphic study with prospective purposes in the El Salado sector, Chicaña parish, Yantzaza canton, province of Zamora Chinchipe. The main objective is the identification of critical elements in the La Pileta waterfall, using a methodology that covers lithochemostratigraphic description, field observations, rock sampling by strata and treatment physical and chemical samples. The study area belongs to the Napo formation, composed of sandstones, black shales and interbedded siltstones. The presence of critical elements such as V, Ni, Cr, Zn, Th was detected and U. The methodology included techniques such as X-ray diffraction, X-ray fluorescence and ICP-MS to carry out the mineralogical description. The concentrations of the critical elements are discussed, relating them to the elements majority and traces obtained from mineralogical and chemical analyses. Finally I know establish the paleoredox conditions through the V/Cr interelemental relationship, which allows interpreting chemostratigraphic profiles and understanding sedimentation processes in the sequence studied.
