A review of 3.66 to 2.77 Ga crustal differentiation in the northern São Francisco Craton, Brazil

, 2022
The Archaean crustal evolution of the northern São Francisco Craton (SFC) reveals significant similarity with Kaapvaal-Zimbabwe and Pilbara, cratons, especially before 3.0 Ga. Likewise, compiled geochronological and Nd-Sr-Hf isotope data suggest that the

Toward an Improved Understanding of the Antarctic Coastal Zone and Its Contribution to Future Global Sea Level

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Geological and isotopic characteristics of granites from the Western Pernambuco-Alagoas Domain: implications for the crustal evolution of the Neoproterozoic Borborema Province

Brazilian Journal of Geology
The Western Pernambuco-Alagoas Domain is a complex tectonic domain of the Southern part of the Neoproterozoic Borborema Province. It borders the Northern margin of São Francisco Craton. U-Pb and Sm-Nd data discussed in this work show that, in the Western

Kamafugite Magma Pathways and Lava‐Flow Paleotopography From Three‐Dimensional Audiomagnetotelluric Imaging Constrained by Borehole Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract An audiomagnetotelluric (AMT) survey was conducted within the Alto Paranaíba Igneous Province, southeastern Brazil, to delineate shallow occurrences of kamafugite, a rare ultrapotassic volcanic rock worldwide. A dense grid of AMT stations was deployed, allowing the construction of a high‐resolution 3D electrical resistivity model ...

Ductile Extrusion Triggered by Continental Collision in NE Brazil

Terra Nova, Volume 38, Issue 4, Page 266-277, August 2026.
ABSTRACT The Borborema Province in northeastern Brazil hosts one of the world's largest strike‐slip shear zone networks, active during the late Neoproterozoic assembly of West Gondwana. Whether these shear zones initiated during active continental collision or as a post‐orogenic response to far‐field stresses remains debated.
