An Animated Tectonic History of Western North America and Southern California.
Tanya Atwater, Dept. Geological Sciences, University of California, Santa Barbara, CA
Summary list of QuickTime animations:
A.Pacific-North America Plate Tectonic History (map views)
1. Pacific Hemisphere, 80 Ma to Present
2. N.E. Pacific and W. North America, 38 Ma to Present
3. California, 20 Ma to Present
4. Southern California, 20 Ma to Present
5. Southern California Paleomagnetic Vectors
6. Southern California, Origin and Dispersal of the Poway Conglomerate
B.Geologic History of the Transverse Ranges, Southern California
1. Mesozoic Subduction
2. Miocene: Rifting and rotation, volcanism and deposition in marine basins
3. Plio-Pleistocene: Oblique Shortening against the "Big Bend"
4. Santa Barbara Channel Oil
B.4. Santa Barbara Channel Oil: Anticlines, Oil Rigs, and Oil Seeps During the last few million years, the sedimentary layers under the channel have been shortened, folded, and faulted. Tar, oil, and gas rise through the pores in the rocks and collect under the anticlinal folds in the clay layers. Where the layers have been broken by faulting or breached by erosion, hydrocarbons escape to the surface forming seeps.
