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.

Machine Learning Model for Assessing Melting Pressure Conditions of the TTG Genesis: Implications for the Timing of the Onset of Global Plate Tectonics

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 11, November 2025.
Abstract Understanding the pressure conditions of the formation of tonalite‐trondhjemite‐granodiorite (TTG) series rocks is important, as these rocks are key constituents of the Archean continental crust. However, the detailed pressure history of Archean TTG gneisses remains ambiguous due to uncertainties surrounding their sources and the effects of ...

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.
