Tectonic Framework of the Arenópolis and Anicuns‐Itaberaí Segments of the Goiás Magmatic Arc Based on 3D Magnetotelluric Inversion

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract The Goiás Magmatic Arc (GMA) is a Neoproterozoic juvenile terrain formed through oceanic‐oceanic and oceanic‐continental subduction. It comprises three main segments: Mara Rosa, Anicuns‐Itaberaí (GMAAI), and Arenópolis (GMAA), whose tectonic evolution and connectivity remain uncertain.

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

Journal of Metamorphic Geology, Volume 43, Issue 9, Page 863-890, December 2025.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

A Recipe for Exotic Continental Fragment Formation: Key Constraints From Numerical Rift Models

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract The Wilson Cycle describes the opening and closing of oceans, generating new plate boundaries at continental rifts, and extinguishing ancient plate boundaries with continental collisions (creating a continental suture). However, the general view of the Wilson Cycle does not fully explain more complex tectonic scenarios.

Tectonic Framework and Low‐Oblique Rifting Kinematics of the Campos Basin, Southeastern Brazilian Margin

Tectonics, Volume 44, Issue 6, June 2025.
Abstract Understanding the tectonic framework of extensional margins is fundamental to unraveling kinematics, basement inheritance and magmatism during rifting. Using regional gravity and magnetic surveys, 2D and 3D seismic reflection data and well information in the Campos Basin, we conducted a systematic structural mapping of the syn‐rift building ...

Crustal and upper mantle structure beneath South America from Rayleigh wave analysis

Geological Journal, Volume 59, Issue 10, Page 2740-2749, October 2024.
Geographical distribution of S‐wave velocity as a function of depth. A review of the S‐velocity structure beneath South America, for the crust and upper mantle, is performed using a recent methodology based on Rayleigh wave analysis, and a new 3D S‐velocity model (from 0 to 400 km depth) is achieved for this study area.

Clay Minerals and Continental‐Scale Remagnetization: A Case Study of South American Neoproterozoic Carbonates

Journal of Geophysical Research: Solid Earth, Volume 129, Issue 10, October 2024.
Abstract The Neoproterozoic carbonate rocks of the Araras Group (Amazon Craton) and the Sete‐Lagoas and Salitre Formations (São Francisco Craton) share a statistically indistinguishable single‐polarity (reversed) characteristic direction. This direction is associated with paleomagnetic poles that do not align with the expected directions for primary ...

The Middle Niger Basin in Nigeria Has a Rift Origin, as Revealed by the Inversion and Modeling of Gravity and Magnetic Data

Earth and Space Science, Volume 11, Issue 3, March 2024.
Abstract The NW‐SE oriented Middle Niger Basin, which is a Campano‐Maastrichtian inland basin has been the subject of debate among geoscientists regarding its origin and development. This paper aims to unravel the basin's origin and evolution by using high‐resolution magnetic, gravity, and topographical data. The integration of aeromagnetic and gravity
