Marine geology and tectonic evolution of the northwestern margin of the California continental borderland
Abstract
The geology and history of the northwestern margin of the California continental borderland are examined using data from seismic-reflection profiling and bottom sampling. It is suggested that the northwestern margin of the borderland along with the western Transverse Ranges was rifted from an original tectonic setting off northern Baja California begining about 18 m.y. ago. During the rifting event, the Franciscan and Great Valley belts underlying the outer borderland were translated northwestward along a ridge-trench transform fault resulting in: (1) a repetition of these belts in the borderland off Southern California, and (2) clockwise rotation and subsequent thrusting of these belts (western Transverse Ranges) against the southern Coast Ranges.
