  • Quaternary Fault and Fold Database of the United States
    Jump to Navigation Quaternary Fault and Fold Database of the United States As of January 12, 2017, the USGS maintains a limited number of metadata fields that characterize the Quaternary faults and folds of the United States. For the most up-to-date information, please refer to the interactive fault map. Pleito fault zone, Western Pleito section (Class A) No. 76a Last Review Date: 2000-07-31 citation for this record: Bryant, W.A., compiler, 2000, Fault number 76a, Pleito fault zone, Western Pleito section, in Quaternary fault and fold database of the United States: U.S. Geological Survey website, https://earthquakes.usgs.gov/hazards/qfaults, accessed 12/14/2020 02:02 PM. Synopsis General: Significant Holocene active south-dipping thrust fault located along the border of the Transverse Ranges and Great Valley. The Pleito fault zone here is divided into two sections, the Western Pleito section and Eastern Pleito section. Detailed studies by Hall (1984 #5935) documented evidence of Holocene thrust fault displacement along the Eastern Pleito section. Hall (1984 #5935) reported a Holocene slip rate of 1.3–1.4 mm/yr for the past 1.5 ka, based on displacement of Hall's alluvial unit Q6(O). The net slip rate for the past 100 ka is 0.3–2.0 mm/yr. Based on observed average dip-slip displacement of 0.77 m and a Holocene slip rate of 1.3–1.4 mm/yr, Hall inferred a recurrence interval of 500-600 yr. Hall (1984 #5935) reported that one and possibly two events have occurred between 500 AD and 1600 AD.

    Lead Forest: Los Padres National Forest Forest Service Endemic: No Abies bracteata (D. Don) Poit. (bristlecone fir) Known Potential Synonym: Abies venusta (Douglas ex Hook.) K. Koch; Pinus bracteata D. Don; Pinus venusta Douglas ex Hook (Tropicos 2011). Table 1. Legal or Protection Status (CNDDB 2011, CNPS 2011, and Other Sources). Federal Listing Status; State Heritage Rank California Rare Other Lists Listing Status Plant Rank None; None G2/S2.3 1B.3 USFS Sensitive Plant description: Abies bracteata (Pinaceae) (Fig. 1) is a perennial monoecious plant with trunks longer than 55 m and less than 1.3 m wide. The branches are more-or-less drooping, and the bark is thin. The twigs are glabrous, and the buds are 1-2.5 cm long, sharp-pointed, and non- resinous. The leaves are less than 6 cm long, are dark green, faintly grooved on their upper surfaces, and have tips that are sharply spiny. Seed cones are less than 9 cm long with stalks that are under15 mm long. The cones have bracts that are spreading, exserted, and that are 1.5–4.5 cm long with a slender spine at the apex. Taxonomy: Abies bracteata is a fir species and a member of the pine family (Pinaceae). Out of the fir species growing in North America (Griffin and Critchfield 1976), Abies bracteata has the smallest range and is the least abundant. Identification: Many features of A. bracteata can be used to distinguish this species from other conifers, including the sharp-tipped needles, thin bark, club-shaped crown, non-resinous buds, and exserted spine tipped bracts (Gymnosperms Database 2010).

Niemi,1 Jamie T. Buscher,2 James A. Spotila,3 Martha A. House,4 and Shari A. Kelley 5 Received 21 May 2013; revised 21 October 2013; accepted 28 October 2013; published 20 December 2013. [1] The San Emigdio Mountains are an example of an archetypical, transpressional structural system, bounded to the south by the San Andreas strike-slip fault, and to the north by the active Wheeler Ridge thrust. Apatite (U-Th)/He and apatite and zircon fission track ages were obtained along transects across the range and from wells in and to the north of the range. Apatite (U-Th)/He ages are 4–6 Ma adjacent to the San Andreas fault, and both (U-Th)/He and fission track ages grow older with distance to the north from the San Andreas. The young ages north of the San Andreas fault contrast with early Miocene (U-Th)/He ages from Mount Pinos on the south side of the fault. Restoration of sample paleodepths in the San Emigdio Mountains using a regional unconformity at the base of the Eocene Tejon Formation indicates that the San Emigdio Mountains represent a crustal fragment that has been exhumed more than 5 km along the San Andreas fault since late Miocene time. Marked differences in the timing and rate of exhumation between the northern and southern sides of the San Andreas fault are difficult to reconcile with existing structural models of the western Transverse Ranges as a thin-skinned thrust system.

These subduction accretion assemblages represent a regional, deeply exhumed, shallowly dipping domain from an ancient slab segmentation system and record the complete life cycle of the segmentation process from initial flattening and compression to final extensional collapse. An important unresolved question regarding shallow subduction zones concerns how the thermal structure evolves during the slab flattening process. New field relationships, thermobarometry, thermodynamic modelling and garnet diffusion modelling are presented that speak to this issue and elucidate the tectonics of underplating and exhumation of the San Emigdio Schist. We document an upsection increase in peak temperature (i.e. inverted metamorphism), from 590 to 700 °C, peak pressures ranging from 8.5 to 11.1 kbar, limited partial melting, microstructural evidence for large seismic events, rapid cooling (825–380 °C Myr)1) from peak conditions and an Ôout and backÕ P–T path.

  • Geology and Oil Resources Along the Southern Border of San Joaquin Valley, California
    GEOLOGY AND OIL RESOURCES ALONG THE SOUTHERN BORDER OF SAN JOAQUIN VALLEY, CALIFORNIA By H. W. HOOTS ABSTRACT The region described in this report includes a foothill belt of the San Emigdio and Tehachapi Mountains along the southern border of San Joaquin Valley., The belt displays portions of the rugged granitic cores of the moun­ tains and alSO rocks Of Eocene, Oligocene, Miocene, Pliocene, and Pleistocene age. Although there is thus a complete representation of the geologic series from the Eocene to the Pleistocene, some portions of the different series are wanting because of major faults and overlaps. The thickness of the Tertiary rocks (Eocene to Pliocene) varies considerably but has a maximum of about 29,000 feet. Miocene and Pliocene rocks cover most of the area investigated. The San Emigdio and Tehachapi Mountains form a structural and physio­ graphic link that connects the Coast Range on the west with the Sierra Nevada on the east. In these mountains there is a gradual eastward transition from the complex folds and faults of the Coast Range to the comparatively simple, gently dipping monocline of the west flank of the Sierra Nevada. The complex structural features in the San Emigdio foothills west of Grapevine Canyon and north of the San Andreas fault provide evidence that this portion of the area has been deformed by stresses with major lateral components from the south stresses which have been responsible for thrust faulting and the development of asymmetrical and overturned folds. Much of the present height of the foothill belt of the San Emigdio and Tehachapi Mountains has been produced by uplift since the beginning of Pleistocene time.

  • Structural Geology and Oil Field Traps of the Western and Southern Margins of the San Joaquin Basin, California September 30 and October 1, 2016
    Structural Geology and Oil Field Traps of the Western and Southern Margins of the San Joaquin Basin, California September 30 and October 1, 2016. Field trip leaders: Thom Davis, Yannick Wirtz, and Greg Gordon Departure time and place: 7:00 am from the AERA Energy parking lot off Old River Road (to the west of the office building; building address is 10,000 Ming Ave., Bakersfield, CA 93311). Return time and place: The trip will return at 6:00 pm each day to the meeting point. Hanging wall deformation near the Pleito thrust fault with Courtney Marshall for scale, Pleitito Creek, San Emigdio Mountains. Guidebook and field trip themes: This guidebook is largely graphical with numerous maps, cross sections, stratigraphic columns, and field photos of the western and southern margins of the San Joaquin basin. Each stop has a short text providing key presentation points and questions for discussion. The goal of the field trip is to show and discuss the geometry, kinematic development, and timing of many of the map-scale structures in the field and some of the major hydrocarbon traps. Most of the cross sections shown are based on well data and surface geology, and of course, are very interpretive at depth and away from the control. Portions of a few of the cross sections are supported by 2D reflection seismic lines but unfortunately these data cannot be reproduced here. Portions of several seismic lines are shown in Davis’ (2015) paper Structural wedge with a hydrocarbon prospective triangle zone, west-side of the San Joaquin Basin (WS), California: implications for untested large traps included at the end of the guidebook.
