Geology of the Kettleman Hills Oil Field, California: Stratigraphy, Paleontology, and Structure

Description: From Introduction: The field work that furnished the basis for this report was begun in 1930 and was continued at intervals until 1934. The anticlinal character of the Kettleman Hills is apparent to even the casual observer, but the many structural complications due to an intricate network of minor faults, at least in North Dome and Middle Dome, are much less obvious. Though it is improbable that these faults have any relation to the occurrence of oil, an attempt was made to map them, not only … more

Paleozoic-Mesozoic Boundary in the Berry Creek Quadrangle, Northwestern Sierra Nevada, California

Description: Abstract: Structural and petrologic studies in the Berry Creek quadrangle at the north end of the western metamorphic belt of the Sierra Nevada have yielded new information that helps in distinguishing between the chemically similar Paleozoic and Mesozoic rocks. The distinguishing features are structural and textural and result from different degrees of deformation. Most Paleozoic rocks are strongly deformed and thoroughly recrystallized. Phenocrysts in metavolcanic rocks are granulated and dra… more

Research in the Geysers-Clear Lake Geothermal Area, Northern California

Description: From abstract: The Geysers-Clear Lake geothermal area lies within the central belt of the Franciscan assemblage in northern California. The structure of this terrane is characterized by northeast-dipping imbricate thrust slices that have been warped and cut by steeply dipping strike-slip and normal faults. Introduction of magma into the crust beneath the Geysers-Clear Lake area can be related to eastsoutheast extension accompanying northward propagation of the San Andreas transform system betwe… more

Tectonically Controlled Fan Delta and Submarine Fan Sedimentation of Late Miocene Age, Southern Temblor Range, California

Description: From introduction: The objectives of this report are to (1) document the stratigraphic framework of the Santa Margarita Formation and part of the Monterey Shale in the southern Temblor Range, (2) interpret the environments of deposition and depositional processes of the above units, and (3) evaluate the influence of tectonism on Santa Margarita sedimentation, with special attention given to testing the hypothesis of Berry and others (1968).
