The nature of the sediments suggests that they have been contributed by the geologically varied physiographic provinces of the Pacific Northwest which drain to the Pacific Ocean via the coasts of Oregon and Washington. Well-sorted, fine-grained sub angular sands cover the continental shelf to a depth of 52 fathoms. Below this depth the sediments grade uniformly to clay-silts on the upper continental slope. Rock outcrops, gravel, and coarse sand are present in the vicinity of Stonewall Bank, along the shelf break, and on the shoals rising from the upper part of the continental slope. Mineralogical immaturity characterizes the nearshore sands and the sand fraction of the finer-grained offshore sediment. Glauconite, calcium carbonate, and organic matter are essentially absent from the sands, but may be abundant in the offshore sediment; glauconite up to 91 percent of the sample; calcium carbonate, 14 percent; and organic matter, 6 percent. Small quantities of organic silica, maily sponge spicules and radiolaria, are irregularly distributed in the fine sediments. Textural considerations suggest that the nearshore sands were deposited in a high-energy littoral environment and may be a late Pleistocene transgressive deposit. Although the glauconite-rich sediments on the offshore shoals and at the edge of the continental shelf attest to little or no deposition, shallow depressions and sea valleys of the upper continental slope may be actively receiving sediment." Purpose: "The purpose ... is twofold: first, to describe in detail the texture and composition of the sediments found in this area; second, to relate the pattern sedimentation to the physical and chemical forces which formed it."

Lineage: Process_Step: Process_Description: A settling tube was used for the mechanical size analysis of the sand samples. Those samples contining pebbles or very coarse sand were sieved, using Tyler standard screens. Samples which contained a noticeable amount of material finer than sand were wet-sieved through a 62 micron screen with a 0.2 percent Calgon dispersing solution. Size analyses were then made by the hydrometer method with the pipette method being used to check selected samples. Total carbon content was determined by total combustion in a Leco induction furnace, couple with a Leco gasoline carbon analyzer. Carbonate carbon was also analyzed gasometrically. Heavy minerals were separated from the total samples by the gravity-funnel technique, with bromoform used as the heavy liquid.
