Evolution of Siderian juvenile crust to Rhyacian high Ba-Sr magmatism in the Mineiro Belt, southern São Francisco Craton [PDF]

open access: yes, 2018
Plutonic rocks from the Mineiro Belt, Brazil record a delayed onset of the transition from TTG to sanukitoid-type magmatism (high Ba-Sr), starting during the Siderian magmatic lull when little juvenile magma was added to the continental crust.

Was the Dry Diagonal of South America a Barrier for Dispersing Pteridaceae (Polypodiopsida) Species Between the Brazilian Atlantic Forest and Amazon Forest?

open access: yesJournal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim We sought to assess how phylogenetic patterns within the fern family Pteridaceae are related to the history of the Amazon Forest and the Brazilian Atlantic Forest, as well as the Dry Diagonal of South America. The age of taxa present in these regions was estimated, as well as those found in previously identified areas of endemism for the ...

Crustal Architecture and Magmatism of the Campos Rifted Margin: Along‐Strike Variability and Segmentation

open access: yesTectonics, Volume 43, Issue 12, December 2024.
Abstract We investigate the crustal architecture and structural domains of the Campos rifted margin in southeastern Brazil, focusing on rifting evolution and segmentation. Based on 2‐D and 3‐D seismic reflection interpretation and potential field modeling, our results reveal an along‐strike variability, in terms of margin architecture and magmatism ...
