New Research Revises Timeline for Americas Tectonic Collision

A new study published in Earth and Space Physics, utilizing magnetic signatures from volcanic rocks in Colombia's Northern Andes, suggests the tectonic collision between Central and South America peaked millions of years earlier than previously understood. The research indicates that significant tectonic deformation had already diminished by the late Miocene, prior to approximately 10 million years ago. This revised timeline offers new insights into the geological history and formation of the Americas, potentially altering models of regional geological evolution and its impact on biodiversity.
