Description:
Abstract:
"A study of sedimentary structures and sediment texture of beach and continental shelf sediments provides a basis for the interpretation of the recent history of sedimentation on the Oregon continental shelf. The texture of various sediment types suggests that coastal rivers supply a considerable quantity of very fine sand in addition to modern mud to the continental shelf. Relict sediments remain uncovered on areas of the shelf not under the influence of major river runoff and are mixed or covered by modern mud and very fine sand where rivers influence shelf sedimentation. Primary sedimentary structures show that sands ranging from very fine to medium in mean grain size are capable of being moved at shelf water depths from at least 38 to 88 meters. No net transport of sand, however, can be determined from these structures. Organic structures apparently are controlled by water depth and/or grain size and sediment type, which determine faunal composition and concentration. At mid-shelf depths fine sand cores are characterized by shell fragments, worm tubes, and worm trails. Beyond 100 meters water depth worm tubes were not found, but worm trails become abundant and large burrow appear in the sediment."
Purpose:
"A study of sediments is undertaken to obtain knowledge of environmental factors responsible for the origin, transportation, deposition, and post-depositional changes of a sedimentary deposit. Sedimentary structures and sediment textures are studied in an attempt to define past and present sources of Oregon continental shelf sediments and to understand the processes responsible for their distribution and deposition."

Process_Description:
Textural data were obtained primarily by particle settling techniques. The coarse fraction (sand) was done by settling tube (Emery, 1938 and Poole, 1957), and the fine fraction (silt and clay) analysis was done by pipette (Krumbein and Pettijohn, 1938). A few samples were too coarse for the settling tube so that sieving at quarter phi intervals was necessary.
