Title: Biostratigraphic Highlights of some Deep Wells from Central-Southern San Joaquin Valley, California: ABSTRACT

Author(s): R. Stanley Beck

Article Type: Meeting abstract

Abstract:

The wells to be discussed are the Kings County Von Glahn No. 1, Sec. 4, T. 23 N., R. 22 E.; Harry H. Magee Amalgamated Happold No. 2, Sec. 15, T. 25 S., R. 24 E.; Continental KCL A-2, Sec. 8, T. 27 S., R. 24 E.; Western Gulf KCL B-45, Sec. 22, T. 29 S., R. 27 E.; Humble KCL D-2, Sec. 15, T. 30 S., R. 27 E.; Ohio KCL A-72-4, Sec. 4, T. 32 S., R. 26 E.; and Humble KCL B-11, Sec. 35, T. 11 N., R. 21 W.

The above wells include more than 21,000 ft. of Pleistocene to Upper Cretaceous (?) sediments that were deposited in non-marine to deep-water marine environments. Thickening and thinning of beds, as well as changes in the biofacies and lithofacies, take place quite rapidly between well locations. In the Ohio KCL A-72-4 and many adjacent wells, "deep water pseudo-Saucesian" foraminiferal species often recur within middle and late lower Miocene intervals. The Humble KCL B-11 and many other wells on or near the major fault systems contain good examples of repetition of faunas resulting from overturned beds and faulting.
