Prospecção mineral no Grupo Paranoá: reprocessamento de dados aerogamaespectrométricos e interpretação integrada a imagens TM - Landsat 5

Abstract: ABSTRACT. The present paper shows a case study of a regional exploration program for gold in the central portion of the Brazilian territory. Airborne gamma-ray and magnetic data of the Brazil-Canada Airborne Project were reprocessed and jointly interpreted with satellite images in a GIS environment. Gold-bearing quartz veins associated to hydrothermal zones in the Paranoá Group are our preferential geological target. Frequently, hydrothermal fluids increase both hydroxides and iron contents in the percolated r… Show more

“…In this way, the interpretation of radiometric and potential field information seems to be very useful for both geologic mapping support and identification of targets for mineral and hydrocarbon exploration (e.g. : Menezes et al, 2006;Carneiro & Barbosa, 2008;Matolin et al, 2008).…”
