Caracterización geológica e identificación de alteraciones hidrotermales y mineralogía aurífera de la labor minera ¨Arenisca¨ perteneciente a la ¨Asociación Minera Asonambile¨ código 501423.

Abstract

Abstract:The currently investigation was carried out in the mining area ¨Arenisca¨ beloging to the Company ¨ASONAMBILE S.A¨ of Nambija neighborhood, wich considered of carrying out a geological characterization and identification of hydrothermal alterations of the aforementioned mining work, for which proceeded to raise the mining work to tape and compass, along with a detailed geological documentation of the walls of the gallery, obtaining representative samples for the respective analyzes in the laboratory such as: x- ray diffraction, and x- ray flourescence, in addition to the production and interpetation of thin films wich provided information of the minerals present in the area and thus be able to determine the type of rock and alteration present in the gallery accompanied by laboratory tests. The results obtained in the laboratory indicate that there are three lithologies that they are along the gallery, wich are skarn, andesites and skimmed tuffs also the presence of propilitic alteration could be determined fundamentally and the potassium alteration less visible. Once all the laboratory test were completed and the lithology and alteration were obtained, a structural geological map of the ¨ARENISCA¨ mining work was ready.
