Short summary
This study explores the erosion and exhumation processes and history of early continental crust hidden within the Amazonian Rainforest. This crust forms part of the Amazonian Craton, an ancient continental fragment. Our surprising findings reveal the area underwent rapid early Cretaceous exhumation triggered by tectonic forces. This discovery challenges the traditional perception that cratons are stable and long-lived entities and shows they can deform readily under specific geological contexts.
