Estudio de prospección geoquímica detallada de la mineralización de vanadio y uranio en el sector Puyango

Abstract

Abstract: The research described in this document was intended to carry out a study of detailed geochemical prospecting in Puyango to delimit the mineralization of the vanadium, uranium and tin. The analyzes of the rock samples were: in situ gamma spectrometry, X-Ray Fluorescence (XRF), X-Ray Diffraction (XRD) and recognition of minerals and rocks in thin sheets. Once the analysis were completed and the statistical interpretation of the data, in the area of study the following concentrations were obtained: Uranium (U) (49 ppm), Vanadium (V2O5) (1380 ppm), and tin (SnO2) (1.05%), which were classified into the categories of threshold, subanomalies and anomaly, however it is necessary to make further measurements or chemical analysis by another analytical technique as ICP, AES or AAS to determine with greater precision and accuracy the values specially the SnO2. The results of the in-situ gamma spectrometer revealed us that the value of the annual natural radiation level is of 15.92 mSv/year (1592 mrem/year), for people outside of the area of study, this level considered means no danger in a short term.
