DOI: 10.1016/j.jsames.2017.01.006
Abstract: Abstract The fragmentation of the West Gondwana during Early Triassic to Cretaceous was marked by intense climatic changes, concomitant with the establishment of extensive desertic/lacustrine systems. These deposits succeeded the emplacement and extrusion of lava… read more here.

DOI: 10.1016/j.lithos.2021.106333
Abstract: Abstract Large amounts of high Ba Sr magmatism can be produced as the result of late accretion or decompression in the final stages of continental arc evolution in orogenic systems and leads to continental crustal… read more here.

DOI: 10.1016/j.precamres.2021.106115
Abstract: Abstract In this contribution we investigate the exhumation T-t path of a nappe system located in the southernmost edge of the Brasilia Orogen, southeast Brazil, developed during the West Gondwana assembly. The allochthons represent an… read more here.

DOI: 10.1016/j.sedgeo.2020.105823
Abstract: Abstract Collisional orogens are one of the most conspicuous features of plate tectonics on Earth. They record the dynamics of continent-continent amalgamation, often confined to linear deformational belts. The Southern Brasilia Orogen is one of… read more here.
