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...
A marine geophysical study using shallow seismic reflection, gravity and magnetic methods of investigation was done for an offshore area near Newport, Oregon. The area is bounded by the latitudes 44°1O' to 44°50' N. and longitudes 124°07' to 124°30' W. The interpretation of observational data showed that the geology of...
This is a summary report of preliminary recommendations for the Oregon State
University: Hatfield Marine Science Center, located in Newport, Lincoln County, Oregon

A deep source-receiver seismic refraction experiment was conducted
on the upper part of the Monterey Deep Sea Fan. The aim of this thesis is
to construct the velocity structure of the upper Monterey Fan and to examine
the lateral seismic velocity variations among the upper, middle and lower
fan subunits....
In April of 1974, Oregon State University conducted a geophysical
survey of the Orozco fracture zone, a Left-lateral transform fault
which offsets the East Pacific Rise off the coast of Mexico near
15°N, 105°W. Magnetic, gravity, bathymetric, and seismic reflection
data were collected during a four day period. This survey...
Nearly 9,000 feet of Cretaceous mudstones, shales, sandstone,
and conglomerates are exposed along the northeast-trending Mitchell
anticline of central Oregon, These rocks are divided into two formations
on the basis of criteria developed in this investigation. The
lower formation, hereby designated the Meyers Formation, is 4,716
feet thick at its...
