South American–Scotia plate boundary zone

E812322

geological region tectonic plate boundary zone

The South American–Scotia plate boundary zone is a complex tectonic region in the South Atlantic where the South American Plate interacts with the Scotia Plate through a network of microplates, transform faults, and subduction-related structures.
