Gravity surveys in the Western Transverse Range Province, Calfornia

Authors


Abstract

The Transverse Range Province of California contains the major east-west trending structural features of southern California. It extends from the coast where the Santa Ynez Mountains plunge into the Pacific Ocean eastward to within fifty miles of the Colorado River. This paper briefly summarizes recent gravity work in that portion of the province west of longitude 118°30′

For the past fifty years this province has been a major region of oil and gas exploration, and production and much geophysical and geological effort has gone into unraveling its stratigraphic and structural complexities. Within the past few years the petroleum industry has conducted numerous offshore geophysical surveys, including detailed gravity work, in preparation for drilling on the federal leases that were opened in the Santa Barbara Channel in 1968.
