... Abstract The Kodiak Shelf basin is part of an extensive forearc region formed by the convergence of the Pacific and North American plates. This convergence and subsequent subduction of the Pacific plate began in earliest Mesozoic time with the development of a volcanic arc (Aleutian Peninsula...

...MICHAEL A. FISHER; MARK L. HOLMES Abstract Reconnaissance seismic-refraction data suggest that the Kodiak shelf is underlain by an ancient shelf-break structural high, which we believe formed during late Paleogene time. During the late Miocene or Pliocene, the present shelf-break structures began...

... of the Bering Sea shelf and the Shumagin-Kodiak shelf. However, the structural and stratigraphic history of these shelves appears to be separate from that of the Alaska Peninsula. The islands of the Shumagin shelf consist largely of a thick flysch sequence of late Mesozoic turbidites and volcanic rocks...

... that the Kodiak shelf area includes possible proximal equivalents of the more distal turbidites. Derivation from the volcaniclastic Mesozoic flysch of the Shumagin-Kodiak shelf is unlikely; more probably the sediments were derived from primary plutonic sources. The turbidites also resemble deposits in the Chugach...

... shelf. On Sanak Island, however, the flysch sequence strikes toward the edge of the Bering Sea Shelf, suggesting that both shelves may form a single structural feature. The Shumagin-Kodiak Shelf formed at the close of the Mesozoic; the Aleutian Trench is no older than Tertiary, and it may be much...
