The South American Plate is a major tectonic plate that forms the western part of South America and a large portion of the South Atlantic Ocean. Its geologic history spans Precambrian time to the present, marked by the formation and breakup of supercontinents like Gondwana and Pangea.123456

The current tectonic framework includes ancient cratons, the Andes Mountains, and basins. The Andes were formed in the Cenozoic Era by the collision of the South American Plate with the Nazca Plate, a process driven by the opening of the Atlantic Ocean. This ongoing subduction and collision continue to shape the continent, resulting in volcanic activity and earthquakes.123456
