Levantamentos magnetotelúricos na Bacia de Salta, Argentina

Abstract

The aim of this work is develop lhe knowledge about the geological structure in Salta Basin sub-surface through MT method. The lhree first chapters does a general descriptíon of Salta Basin, presenting the more important formations, the slructural out/ine, tectonic evolution and his historica/ geological context. Also, we describe lhe known petroliferous syslems and did a brief historical about hydrocarbon production in this region. ln the next chapter, we show the physical and mathemalical theory subjacent to MT method, the e/ectromagnetic fields origin of interest and how to obtain sub-surface resistivity information with this fields. The next chapters dealing with a case study applied on Tucumán region, where we use 1 D modeling do determine the resistive slructure on surface up to basement, contributing to a more understanding about Salta Basin geology.
