Modeling of Airbone Data (Magnetic and Electromagnetic) of Cristalino Cu-Au Deposit, Carajás, Pará, Brazil

Abstract

The Cristalino Cu-Au deposit is located in Carajas Mineral Province. The area of the deposit was covered by an airborne survey (magnetic and time domain electromagnetic) in order to identify the most conductive areas. Six resistivity depth images were built for these data, using the software ImagEM and the magnetic data was processed and interpretation was based on the Analytical Signal. The ImagEM software is under development by the Electromagnetic Interpretation Research Group of Universidade de Brasilia. ImagEM showed very good results for the Cristalino area, where the low resistivity core has a good correlation with the deposit.
