Abstract

The Murray fracture has been thought to extend ashore into the Transverse Ranges of California, but a geophysical study shows no evidence of structural continuity between these features. Instead, basement morphology typical of the Murray fracture zone ends where its known magnetic and bathymetric expression dies out. Similarly, east-west Transverse Range structures change direction so that they are parallel to the northwest trend of the coast rather than crossing the continental shelf and slope. The lack of continuity suggests an independent development of the Transverse Ranges since at least mid-Tertiary time along an older structural trend continuous with the Murray fracture zone. Possibly a fundamental lineament in the crust, an extension of the Murray, inactive since at least the mid-Tertiary, provided a convenient trend for development of the Transverse Ranges in response to deformation along the San Andreas fault system. The Murray fracture zone is thought by some authors to be a transform-fault. The transform-fault hypothesis alleviates some difficulties that arise in explaining the origin of the zone by transcurrent faulting but equivalent uncertainties seem to accompany the newer explanation.
