Prospección geoquímica de elementos de lasTierras Raras del granito Tres Lagunas sector La Voladora

Abstract

Abstract: The present research work is based on the geochemical prospection of Rare Earth elements of the Tres Lagunas Granite of the Voladorasectorin the Saraguro canton. The purpose of the investigation seeks to discovermineralized zones, that is, those that present geochemical anomalies. Prospecting is carried out by sampling rocks in the study area by prior preparation of a sampling mesh that allows representative areas to be determined. Fifteen samples were taken to identify the presence of Rare Earth Elements and mineralogicalanalysis was carried out using X-Ray Diffraction (XRD), chemical analysis using X-Ray Fluorescence (XRF)and analysis using an Inductively Coupled Plasma Spectrometer with Optical Detector (ICP-OES).It was determined that the present lithology corresponds mostly to quartz diorite, granodiorite, granite, diorite. Mineralogically, quartz, albite, muscovite is found among other minerals, considering the X-Ray Fluorescence analysis, major elements and trace elements that present concentrations higher than the average Clarke in the crust were determined, such as Molybdenum, Cerium, Lead, Bismuth. and uranium. Regarding the concentrations of elements of the Rare Earths, it was established that Lanthanum presents anomaly values (115 ppm) and elements such as Cerium (483.26 ppm), Neodymium (245.35 ppm), Gadolinium (6.95 ppm), Ytterbium (2.20 pm), Yttrium (51.25 ppm), Thorium (67.80 ppm) and Uranium (3.23 ppm) exhibit sub-anomaly concentrations in the study area.
