ABSTRACT The western Aleutian Islands, which extend from Great Sitkin Island westward to Attu Island in the eastern hemisphere, form a transition zone between oblique subduction and strike-slip motion between the Pacific plate and the North America plate along the Aleutian margin. maximum age for early Aleutian-Arc volcanism is suggested by the ages of rocks included in the Meshik Arc on the Alaska Peninsula (Wilson, 1985), the rocks of which appear to directly correlate with those of the Lower Series in the Aleutian Islands.
