The Coalinga Anticline is asymetrically folded and plunges 10/sup 0/ to the southeast. Along the E. flank, the beds dip from 12/sup 0/ to 16/sup 0/, while dips of 60/sup 0/ to 85/sup 0/ characterize the steeper SW. flank. The anticline interrupts the dominant geologic structure in the area, the regional homocline, which dips generally northeastward. Stratigraphically, the white weathered shale of the Eocene Kreyenhagen is unconformably overlain by the middle Miocene Temblor. The Temblor is, in turn, unconformably overlain by the Pliocene Etchegoin in the foreground. The upper Miocene Santa Margarita, overlies the Temblor and is completely truncated to the southeast of Cartwheel Ridge. A sealing shale at the base of the Pliocene provides the trapping mechanism for the Temblor. One mile to the north, on the axis of the Coalinga Anticline, oil was first discovered at Coalinga in the Oil City field during 1890 (now abandoned). Forty-four wells were drilled and the field reached a cumulative production of over 2.5 MM bbl of 28/sup 0/ oil from the Cretaceous Moreno.
