Charcot plate
Fragment of the Phoenix tectonic plate fused to the Antarctic Peninsula
From Wikipedia, the free encyclopedia
The Charcot plate was a fragment of the Phoenix plate.[1] The subduction of the Charcot plate, beneath West Antarctica, stopped before 83 Ma, and became fused onto the Antarctic Peninsula.[2] Researchers have suggested that there are remnants of the western part of the Charcot plate in the Bellingshausen Sea.[2]
