Available in PDF, EPUB and Kindle. Book excerpt: Four cross sections are balanced and retrodeformed to 250±50 ka and 975±75 ka to yield crustal shortening amounts and rates for the western Transverse Ranges of California. The cross sections compare the shortening that occurs along a transfer zone in which displacement is transferred eastward from a surface reverse fault (Red Mountain fault) to a blind thrust, to a combination of both a surface reverse fault (San Cayetano fault) and the blind thrust, and to a surface reverse fault (Modelo lobe segment of the San Cayetano fault). Deformation can be separated into three phases: (1) pre- Vaqueros (pre-late Oligocene-early Miocene) tilting in the hanging-wall block of the Oak Ridge fault that is coincident with normal faulting farther south at Big Mountain and to the east in the east Ventura basin, (2) Pliocene reverse faulting and folding, and (3) Quaternary deformation. Crustal shortening rates have increased through time. For the four cross sections, crustal shortening rates were 4±4 mm/y, 5±2 mm/y, 6±5 mm/y, and 14±6 mm/y for the interval between 250 ka and 975 ka. Since 250±50 ka, crustal shortening rates increased to 23±12 mm/y, 29±7 mm/y, 27±11 mm/y, and 25±11 mm/y. But crustal convergence rates determined by Global Positioning System (GPS) surveys, taken over an interval of 2.7 years, indicate a shortening rate of only 7±2 mm/y across the basin. The discrepancy between a rate of strain over a short, recent time period of little seismic activity, and a faster rate determined by the offset of bedrock horizons over several hundred thousand years indicates that much of the present crustal movement is being stored as elastic strain that could result in the release of energy in damaging earthquakes.

This book was released on 1988 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Upper Ojai Valley is a tectonic depression between opposing reverse faults, Its northern border is formed by the active, north-dipping San Cayetano fault with 6.0 km of dip-slip displacement in the Silverthread oil field and 2.6 km displacement west of Sisar Creek; the fault dies out farther west in Ojai Valley. The southern border is formed by the late Quaternary Sisar-Big Canyon-Lion fault set which dips south and merges into the Sisar decollement within the south-dipping, ductile Rincon Formation. Folds with north-dipping axial planes, including the Lion Mountain anticline and Reeves syncline, are middle Pleistocene or older and are related to movement on a frontal strand of the San Cayetano fault. In late Quaternary time, the Sulphur Mountain anticlinorium and the Big Canyon syncline began forming as fault-propagation folds, followed closely by the ramping of the south-dipping faults to the surface over the Saugus Formation. To the east, the San Cayetano fault locally overrides and folds the south-dipping faults. Cross-section balancing shows that the Miocene and younger rocks above the Sisar decollement are shortened 6.7km more than the more, competent rocks below. A solution to this bed-length problem is that the decollement becomes a ramp and merges at depth with the steeply south-dipping Oak Ridge fault. This implies that the Sisar, Big Canyon, and Lion faults are frontal thrusts to the Oak Ridge fault. The total horizontal shortening since Pliocene time is 14.5km. Recently-drilled wells in the Chaffee Canyon oil field, Ventura County, California, reveal that the Wiley Canyon producing anticline formed in the Pleistocene prior to much of the displacement on the Oak Ridge fault. The east and west plunge in part predates deposition of the Vaqueros Formation of early Miocene age. The dip on the south strand of the Oak Ridge fault increases eastward across the field from 70-75° to 83-85°; farther east, the fault plane is overturned and dips north. The Torrey fault can be traced northwest under a landslide east of Wiley Canyon anticline but not farther northwest.
