This book was released on 1981 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface and subsurface mapping are combined to determine the structure and geologic history of the eastern half of the Simi fault in the Simi Valley area. Upper Cretaceous rocks exposed south and east of the Simi Valley are overlain unconformably by the nonmarine Simi Conglomerate of Paleocene age. The Marine Paleocene unit conformably overlies and is locally interbedded with the Simi Conglomerate; it is composed of Simi Conglomerate clasts that were reworked during a marine transgression. Siltstone of the Santa Susana Formation conformably overlies the Marine Paleocene unit, disconformably overlies the Simi Conglomerate, and was deposited in a deepening marine basin. The overlying Llajas Formation was deposited during a marine regressive-transgressive-regressive cycle. The latter regression continued in late Eocene time with deposition of the overlying nonmarine Sespe Formation. Extension and normal faulting followed deposition of the Sespe, with the early Miocene Vaqueros Formation being deposited unconformably over the Sespe. Formation of the Simi anticline and Simi fault occurred after deposition of the Vaqueros and prior to the deposition of the Conejo Volcanics, and resulted in 3850 feet (1173 m) of separation along the Simi fault in the western part of the study area. The Conejo Volcanics were erupted into a structurally controlled marine basin in the Santa Monica Mountains-Conejo Hills area during the middle Miocene. The flows extended northward over the Simi fault to the southwest flank of Big Mountain. Sedimentary rocks of the Topanga Formation were deposited prior to, during, and after deposition of the Conejo Volcanics. The Neogene Topanga, Modelo, and Pico Formations in the Simi Valley area are thin, discontinuous, and bounded by unconformities, with the late Miocene to early Pliocene Towsley Formation being entirely absent. This implies that the Neogene in the Simi Valley area was characterized by shallow-water sedimentation interrupted by periods of nondeposition and erosion, and is in contrast to the conformable, predominately deep-water Neogene sequence present in the East Ventura basin. The Neogene sequence contains evidence that the Simi Valley became a structural high during the early Miocene and remained elevated through the Pliocene. Formation of the south-dipping Marr, Brugher, Llajas, Ybarra Canyon, and possibly the Corredo faults is assumed to have occurred during Pico deposition, coincident with the formation of the south-dipping Frew fault in the Aliso Canyon area. Movement along the present trace of the Simi fault truncated the Marr fault and is assumed to have occurred subsequent to Pico deposition. The northdipping C.D.L.B., Strathearn, and Joughin faults are inferred to have formed at this time, and ceased movement prior to the deposition of the Saugus Formation. Folding of the Happy Camp syncline occurred after deposition of the Saugus, possibly in response to the same northeast-southwest-oriented stressfield that formed the Santa Susana fault. The Simi fault cuts older alluvium east of Tapo Canyon, but does not cut slump blocks of Conejo Volcanic that overlie the fault north of Tierra Rejada Valley.

Book Synopsis Areal Geology of the Western Mojave Desert California by : U.S. Department of the Interior
Download or read book Areal Geology of the Western Mojave Desert California written by U.S. Department of the Interior and published by CreateSpace. This book was released on 2014-02-23 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mojave Desert in southeastern California is a wedge-shaped region having its apex toward the west. This report deals with the western part of the desert – a part that is characterized by interior drainage and is sharply delineated by mountain ranges on both the southwest and northwest. The part mapped geologically inc1udes about 7,200 square miles between latitudes 34°34' and 35°30' N. and longitudes 117° and 119° W., or parts of Kern, Los Angeles, and San Bernardino Counties. The center of the region lies about 70 miles airline north-northeast of Los Angeles. Fieldwork was done during the spring, autumn, and winter months from 1952 to 1955 and during short intervals from 1956 to 1959. This report and map represent part of a geologic investigation by the U.S. Geological Survey of the known and potential deposits of borate minerals in the southern California desert regions. The primary purpose of this report and the geologic map is to provide a geologic background for the exploration for possible concealed borate deposits in the western Mojave Desert, based upon (1) the geology of the known deposits of these minerals within the region, (2) the areal geology of the region, and (3) the subsurface geology as determined insofar as possible from logs of exploratory test holes, mine workings, and geophysical data. Available logs of test holes so used, including those drilled for petroleum and some for water, and of borate mine shafts are summarized in tabulated form; the gravity geophysical data are published separately. The resulting geologic data are of use for many secondary purposes, such as exploration for other commodities, including petroleum and gas, and in evaluation of ground-water conditions.
