Geophysical and geological evidence of Precambrian evaporites within western São Francisco basin – A working hypothesis for gas and oil exploration to unveil an Earth´s secret of central Brazil

Abstract

Geological and geophysical evidence is presented for the highly probable local presence of evaporites within the Precambrian Sao Francisco basin of Brazil. This working hypothesis has obvious implications both for the exploration of gas and oil, and for more general scientific and macroeconomic questions.
