Analysis of recent geological and geochronological data from the basement of the South
American platform indicates that the Brasiliano orogenic collage took place in four distinct …

During the last 15 years, more attention has been paid to derive analytic formulae for the
gravitational potential and field of polyhedral mass bodies with complicated polynomial …

We present a tomographic model of the crust, upper mantle and transition zone beneath the

Structural data collected in the Carajás Province region led to a new interpretation of the
southeastern Amazonian Craton geotectonic evolution. The purpose of this article is to …

Abstract The Dahomey belt in Togo and Benin is an important segment of the larger West
Gondwana Orogen. Here, we review the geodynamic evolution of the Dahomey belt and …

Fault zones commonly have spatially variable fault rocks and brittle structures. Differing fault-
rock attributes may retard or increase cross-and along-fault permeability. Our work analyzed …

This review summarizes the results of nearly 50 years of application of geophysical data to
study tectonic problems in Borborema Province (BP), Northeastern Brazil. Much information …

Abstract The Cretaceous-Paleogene Boundary (KPB), the only known global impact ejecta
