This part of SIM 3302 presents data for folds for the geologic and geomorphic map (see sheet 10, SIM 3302) of the Offshore of Coal Oil Point map area, California. The vector data file is included in "Folds_OffshoreCoalOilPoint.zip," which is accessible from http://pubs.usgs.gov/ds/781/OffshoreCoalOilPoint/data_catalog_OffshoreCoalOilPoint.html. This map area is in the Ventura Basin, in the southern part of the Western Transverse Ranges geologic province, which is north of the California Continental Borderland (Fisher and others, 2009). Significant clockwise rotation--at least 90 degrees--since the Miocene has been proposed for the Western Transverse Ranges province (Luyendyk and others, 1980; Hornafius and others, 1986; Nicholson and others, 1994), and this region is presently undergoing north-south shortening (see, for example, Larson and Webb, 1992). In the eastern part of the map area, cross sections suggest that this shortening is, in part, accommodated by offset on the North Channel, Red Mountain, South Ellwood, and More Creek Fault systems (Bartlett, 1998; Heck, 1998; Redin and others, 2005; Leifer and others, 2010). Crustal deformation in the western part of the Offshore of Coal Oil Point map area apparently is less complex than that in the eastern part (Redin, 2005); the western structure is dominated by a large, south-dipping homocline that extends from the south flank of the Santa Ynez Mountains beneath the continental shelf.
