Structural geology of the Morales Canyon and Taylor Canyon region of the Cuyama basin, southern Coast Ranges, California

Creator:: Calhoun, Jeannette A.
Abstract:: Early structural influences on the Cuyama basin include Oligocene extension followed by early Miocene wrench faulting. Evidence of wrench faulting is obscured by Pleistocene thrust faulting. Detailed surface and subsurface structural analysis was used to separately examine the effects of each structural regime. The northwest-trending, right-lateral Russell fault was the...
