Aplicação de sensoriamento remoto geocondutivímetro EM-34 para prospecção de ouro nas imediações da Mina da Bossoroca, Vila Nova do Sul, RS

Abstract

This study is located in a gold mining area. This location is in the Sequences Campestre and Arroio Lajeadinho at the geomorphologic unit Escudo Sul-rio-grandense in the southwest region of the estate of Rio Grande do Sul, between the cities of Caçapava do Sul and Vila Nova do Sul. It aims to acquire relevant information regarding geology, prospecting, topographic and structural conditions to enrich the geological knowledge of the area and therefor contribute to the acquisition of more information, to better understand the geological context of the area and so develop the study of gold mining. The methodology involves the use of remote sensing with satellite imagery and data acquired in the field, later to be processed generating maps and models in the detail scale of the gold mining area. Concomitantly have been made a geophysical study of the induced electromagnetic method (EM), which results in the differentiation of the lithologies in this complex and the direction of prospecting for rocks with resistive character that have the aspects related to the characteristics of a ambient for the genesis of gold in quartz veins.
