The Pacific offshore margin displays a
wide range of structural styles as graphically represented by the marine
seismic profiles acquired as a part of the oil and gas exploration boom of the
1970's and 1980's. Here we display a sampling of those lines chosen to represent
the depositional and deformation history of the various coastal provinces.
In the
South of the Mendocino fracture zone the

south to Point Conception. South of San Francisco, the absence of major
strike-slip faulting allows a clearer picture of the convergent influence.
South of Point Conception, the major
tectonic influence has been the rotation of the
