Sources, dispersal, and contributions of fine-grained terrigenous sediments on the Oregon and Washington continental slope

Creator:

Krissek, Lawrence A.

Abstract:

Holocene hemipelagic deposition of terrigenous silts and clays dominates sedimentation on most of the Oregon and Washington continental slope. The sources of these sediments, the mechanisms causing sediment dispersal, and the relative contributions of the various continental sources to the marine deposits have been investigated using quantitative mineral and geochemical...

Continuous seismic profiling investigation of the southern Oregon continental shelf between Cape Blanco and Coos Bay

Creator:

Mackay, Angus James

Abstract:

A structure map was constructed of the continental shelf between Cape Blanco and Coos Bay, Oregon, exclusively from an interpretation of approximately 700 km of continuous seismic profiles. At least ten discernible seismic units were mapped on the bases of acoustic appearance, lateral continuity, angular unconformities, and faults. The offshore...
