Description Stratigraphy of the Punchbowl Formation, Cajon Valley, southern California FB2

Stratigraphy and paleontology of the middle to late Pleistocene Manix Formation, and paleoenvironments of the central Mojave River, Southern California January.

The north frontal fault system of the San Bernardino Mountains is made up of a number of disparate structural elements, each of which accommodates range-front deformation in a manner dictated by its geometry.

A two-stage history of late Cenozoic structural development is proposed for the northwestern San Bernardino Mountains: the range was first uplifted on low-angle structures and later.

The San Bernardino 30'x60' quadrangle, southern California, is diagonally bisected by the San Andreas Fault Zone, separating the San Gabriel and San Bernardino Mountains, major elements of California's east-oriented Transverse Ranges Province.

Included in the southern part of the quadrangle is the northern part of the Peninsular Ranges Province and the northeastern part of the oil-producing.

The San Joaquin Valley is a sediment-filled depression, called a basin, that is bound to the west by the California Coast Ranges, and to the east by the Sierra Nevadas.

It is classified as a forearc basin, which basically means that it is a basin that formed in front of a mountain range.

Barstow Formation, Cajon Valley Formation, and Temblor Formation). Methods: To determine if C 4 grasses were present in middle Miocene horse diets, we analysed stable carbon (δ13C) and oxygen (δ18O) isotope values from the enamel of the fossils.

Early work in Cajon Valley referred to the formation as Punchbowl, due to its similar appearance to the Punchbowl Formation at Devil's Punchbowl (northwest along the SAf).

However, paleontological work placed Cajon Valley strata in the Hemingfordian-Barstovian ( Ma), as opposed to the Clarendonian-Hemphillian ( Ma) Punchbowl Formation. Formation. The Upper Eocene consists of two formations that interfinger into each other: ii Kreyenhagen Shale in the Coalinga district in the north, and 2) The Tejon Formation mostly sands and some shale at the south end ofthe valley.

The Point Rocks sandstone is a tongue of the Tejon Formation in the Kreyenhagen Shale that extends as far north. Woodburne, M.O., and Golz, D.J.,Stratigraphy of the Punchbowl Formation, Cajon Valley, southern California: Berkely, University of California Publications in Geological Sciences, v.

Because unit 6 of the Cajon Formation (ca. 13 Ma) and unit 5 of the Crowder Formation ( Ma) are the youngest units obviously truncated by the Cajon Valley and Squaw Peak faults, respectively, and the Ma Phelan Peak Formation is not offset by these faults, these two faults were active sometime between 13 and 9 Ma, respectively and Ma.

Stratigraphy of the San Joaquin Valley. Geologic Formations. The stratigraphy of the San Joaquin Valley is very confusing, as the names of many of the formations change as you go from one side of the valley to the other.

Much of the stratigraphy was formalized by Ralph Arnold (), who was lead author in on USGS papers on the Coalinga (Bulletin ) and McKittrick-Sunset oil.

The Punchbowl fault is an ancient segment of the San Andreas System that was active between 1 and 4 Ma and exhumed from a depth of 2–4 km, thereby providing the opportunity to study processes along.

The Valley Springs formation rests unconformably on the Ione sandstone. It consists of a fluvial sequence of rhyolitic ash, sandy clay and siliceous gravel. The material is acidic in reaction (pH to ) and pale yellow to white in color.

The formation is generally considered to be of Miocene age, although Axelrod () considers it to be. Hence, the offset along the Squaw Peak fault that now separates the units was probably on the order of at least several tens of kilometers.\ud \ud Because unit 6 of the Cajon Formation (ca.

13 Ma) and unit 5 of the Crowder Formation ( Ma) are the youngest units obviously truncated by the Cajon Valley and Squaw Peak faults, respectively, and. Westward it is overlain by the Punchbowl formation and alluvium, but it is assumed to meet the San Jacinto fault beneath the Punchbowl formation between the forks of Big Rock Creek, near the point where the crush zone along the San Jacinto fault begins to widen.

East of the area mapped (fig. 3) the Fenner fault trends eastward to the San Andreas. The most widespread outcrops in Cajon Valley are nonmarine sandstones and mudstones variously called "Cajon beds", Punchbowl Formation, or Cajon Formation.

We accept the latter. This formation, host to the CPDDH, yielded late middle Miocene to late Miocene vertebrate fossils (W•b•e and Golz, ). The Cajon Formation apparenfiy.

The DOSECC well in Cajon Pass encounters two sedimentary units: the uppermost is Unit 5 of the Cajon (Punchbowl) Formation; the lower has not been identified.

To help identify the lower unit, fragments of fossil tooth and bone were separated from kg of cuttings recovered from ‐ m in the well by washing, sizing, heavy liquid separation and hand sorting.

The most diagnostic. A new genus of hypsodont equid, Scaphohippus, is recognized from the Green Hills Division (Ba1), Second Division (Ba1), and Barstow Faunas (Ba2) of the medial Miocene Barstow Formation, as well as from Ba1 and Ba2 faunas in the Punchbowl Formation of California, the Tesuque Formation of New Mexico, the Pawnee Creek Formation of Colorado, and the Olcott Formation.

Age determination based on biostratigraphic correlation, faunal zones from the Barstow Formation, and paleomagnetic stratigraphy indicate that the Crowder Formation was deposited between and Ma or younger (Reynolds et al., ), and the Cajon Valley Formation between and Ma; however, fossils do not occur throughout the.

In the Spring Mountains of southern Nevada and the adjoining Death Valley region of California, however, the thicknesses are much more variable. In the northern part the Monte Cristo limestone, which as defined by Hewett () appears to be largely of lower Mississippian age, is feet thick (85) and in the southern part it is possibly as.
