...Ann Tipton Abstract Exceptional foraminiferal sequences of Zemorrian and Saucesian (Oligocene-Miocene) age occur in the subsurface of the southwestern San Joaquin Valley in sediments referable to the Pleito and Temblor Formations. Downdip from the basin margin, these subsurface sequences...

... in the local fold axes and reverse faults of Pliocene age and younger. Second, at the extreme southern reaches of the SSJV in the San Emidio, Los Lobos, Pleito, Wheeler Ridge, and North Tejon fields, another systematic, but localized, reorientation in the stress field indicates an abrupt change...

...Peter G. Decelles ABSTRACT The Eocene to lower Miocene fill of the southern San Joaquin basin contains three complete depositional sequences—the Tejon, San Emigdio, and Pleito—each of which corresponds to a formal formation. The Tejon sequence (lower to middle Eocene) is marine and incorporates...

... along the older, more southerly structures. The main objective of our soils work is to assist in the correlation of late Pleistocene and Holocene alluvial surfaces and to establish a relative chronology. On the basis of field mapping and soils analysis, four major late Pleistocene–Holocene units...

... of Ventura basin faults. Santa Susana fault ( Fig. 2 ).—The Tide Water Associated Oil Company’s Porter well, No. 12 in the Aliso Canyon oil field, penetrated 400 feet of fractured Modelo brown shale of middle Miocene age, after going through the massive Topanga 5 sandstone of lower Miocene age...

... southwestward into the subsurface ( Pence, 1985 ), where it is penetrated by wells at Elk Hills and Buena Vista fields. Carneros submarine fan sandstone contains detrital radiolarian chert and porphyritic felsite that were likely sourced from the exposed Mesozoic Franciscan subduction complex and Cretaceous...

...George M. Cunningham ABSTRACT This paper treats of the location and economic importance of the field. The formations described are of Miocene and Pliocene age. The Wheeler Ridge anticline is an asymmetric fold, the north flank having the steeper dips. The structure is closed, the highest part...

...T. W. Dignes; D. Woltz ABSTRACT In the onshore area of California, 403 exploratory wells were drilled during 1980; 133 were successfully completed as producers. Five new gas fields and 4 new oil fields can be called ‘significant new discoveries’ found by exploratory drilling during 1980...

... anticline. The origin of family 22 is unclear based on locations of the pools, but it is presumed to come from the Buttonwillow depocenter, as discussed below ( Figures 9 , 13 ). Family 20 contains 10 samples from the San Emidio Nose (1), Pleito Ranch (5), Elk Hills (1), and Los Lobos (1) fields...

One well in the Pleito field also has an analysis indicating the possible presence of protected water at 730 m (2394 ft). Because the map in Figure 4 does...
