Earth:Insular Plate
From HandWiki
Short description: Ancient oceanic plate
The Insular Plate was an ancient oceanic plate that began subducting under the west-coast of North America around the early Cretaceous period. The Insular Plate had a chain of active volcanic islands that were called the Insular Islands. These volcanic islands, however, collided then fused onto the west-coast of North America when the Insular Plate jammed then shut down ending the subduction zone.[1]
