Uplifted Trench Sediments: Southwestern Alaska-Bering Shelf Edge

Cretaceous turbidites are discontinuously exposed for 1700 kilometers along the continental margin of southwestern Alaska and the Bering shelf edge. Paleocurrent flow parallel to exposure patterns and the abundance of primary andesitic volcanic detritus suggest deposition in an oceanic trench. This Cretaceous trench bordering the continent was superseded by the Aleutian arc-trench in the earliest Tertiary.
