Wandering terranes in southern Alaska: The Aleutia Microplate and implications for the Bering Sea
Michael S. Marlow, Alan K. Cooper
1983, Journal of Geophysical Research B: Solid Earth (88) 3439-3446
Paleomagnetic and geological data suggest that much of southern Alaska is a collage of tectonostratigraphic terranes which originated in Mesozoic time at paleolatitudes far south of their present position. The time of ‘docking’ of the terranes against cratonic Alaska is critical to defining their amalgamated size and extent during their...
