Marine geology of the continental margin off southern Oregon

Creator:: Spigai, Joseph John
Abstract:: The continental margin off southern Oregon, which includes the shelf and slope from Cape Blanco to the Oregon-California border, exhibits a distinctive marginal-plateau structural pattern which divides the margin into the continental shelf, the upper continental slope and its associated benches, and the lower continental slope. Lutum transport and deposition...

Sedimentary texture--a key to interpret deep-marine dynamics

Creator:: Allen, David William
Abstract:: The processes responsible for transporting and depositing thick sections of coarse-grained terrigenous clastics on the abyssal floor and for forming associated sedimentary structures are still conjectural. Many workers attribute coarse deep-sea sediments and their probable lithified equivalent, the graywackes of flysch deposits to some type of density movement. Deductions concerning...

Sediment transport on the northern Oregon continental shelf

Creator:: Harlett, John Charles
Abstract:: The distribution of surface sediments on the northern Oregon continental shell is characterized by a nearshore sandy facies and an outer shelf muddy facies, separated by a mid-shelf zone of mixed sand and mud. Currents which have been measured at 130 centimeters above the bottom indicate that the distribution of...

Deformation in the Peru Trench, 6⁰-10⁰S

Creator:: Prince, Roger Allan
Abstract:: Detailed surveys of several segments of the Peru Trench show that the region between 6° to 10⁰ S is an area of recent deformation. Seismic reflection records across the axis of the trench show faulting, uplift, and tilting of the sedimentary fill and the acoustic basement. Uplift of the acoustic...

Peruvian deep-sea sediments : evidence for continental accretion

Creator:: Rosato, Victor Joseph
Abstract:: In order to determine whether the sediments found on the landward wall of the Peru Trench are accreted Nazca Plate sediments, the clay mineralogy and organic carbon contents of 52 surface samples were submitted to factor analysis. Q-mode factor analysis resolved the data from the Nazca Plate and Peru continental...

Morphology, shallow structure, and evolution of the Peruvian continental margin, 6⁰ to 18⁰ S

Creator:: Masias Echegaray, Juan Antonio
Abstract:: Detailed bathymetric survey data were collected along the Peruvian continental margin and were compiled by the author and other investigators to construct a new bathymetric map for the area between 6° to 18°S latitude. Based on this map and individual bathymetric profiles, the continental shelf topography is essentially flat. Four...

Holocene sedimentation and potential placer deposits on the continental shelf off the Rogue River, Oregon

Creator:: Chambers, David Marshall
Abstract:: Changes in sea level during the past 20,000 years are recorded in sediments taken from the continental shelf off the Rogue River, Oregon. Sea level has risen approximately 125 m. during the Holocene (Curray, 1965) and the general transgression has been interrupted by several stillstands and minor regressions. Box core...

The structure and sediments of Surveyor Deep-Sea Channel

Creator:: Ness, Gordon Everett
Abstract:: Surveyor Deep-Sea Channel extends for approximately 700 km over the northern Alaskan Abyssal Plain. It originates near the base of the continental slope opposite Dry Bay and Alsek Strath and terminates in the Aleutian Trench south of Kodiak Island. East of Giacomini Seamount, the axial gradient of the channel is...

Chile trench : extensional rupture of oceanic crust and the influence of tectonics on sediment distribution

Creator:: Schweller, W. J. (William John)
Abstract:: Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...

Sediment textures and internal structures : a comparison between central Oregon continental shelf sediments and adjacent coastal sediments

Creator:: Roush, Robert Cornelius
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...

Calcium carbonate, organic carbon, and quartz in hemipelagic sediments off Oregon : a preliminary investigation

Creator:: Peterson, Robert E.
Abstract:: An analysis of the amounts of calcium carbonate, organic carbon, quartz, and the rates of sediment accumulation in hemipelagic sediments off Oregon has revealed that the accumulation rates of the total sediment, organic carbon, and quartz were at least twice as high in the late Pleistocene as they were during...

The relationship between sedimentation rate and total organic carbon content in ancient marine sediments

Creator:: Ibach, Lynne E. Johnson
Abstract:: Sedimentation rate could become a new exploration tool for evaluating the source rock potential of sedimentary basins in frontier regions. Petroleum source rocks are defined on the basis of total organic carbon by weight percent. An analysis of Deep Sea Drilling Project (DSDP) cores indicates that there exists quantitative relationships...
