Paleo-oceanographic controls on lithofacies and biofacies patterns in Neogene basins of California
Collision of the Pacific and North American plates (about 29 Ma) and subsequent birth of the San Andreas transform system led to the rapid formation of a Miocene borderland stretching across 20/sup 0/ of latitude from Baja California, Mexico, to northern California. The resulting complex of basins, ridges, and islands was much larger than the modern borderland off southern California and was astride an unusually dynamic oceanographic and climatic hinge line dominated by the California Current. Studies of borderland basins have generally emphasized the role of tectonism in controlling basin evolution, including aspects of basin stratigraphy. This paper focuses on faunal and lithofacies evidence of the paleo-oceanographic history of this region and the role of global and provincial oceanographic and eustatic events in dictating the strikingly similar stratigraphic pattern expressed throughout the Neogene borderland.
