Uranium-series dating of some pleistocene marine deposits in Southern California
Analyses of uranium isotopes and their long-lived daughter products showed evidence of uranium migration in most of the 22 fossil mollusk shell samples from marine terrace deposits in southern California. Two samples, however, remained an ideal closed system as indicated by concordant 230 Th/ 234 U and 231 Pa/ 235 U dates. The closed-system age of the lowest exposed marine terrace deposit along part of the mainland coast of southern California is 69 000 ± 10 000 yr, and correlation of this discontinuous deposit is afforded between the Newport Beach-Laguna Beach area and the Palos Verdes Hills. Some mollusk shell samples were dated by the open-system model; the remaining samples were found to be unsuitable for uranium-series dating.

Map showing recently active breaks along the San Andreas and related faults between Cholame Valley and Tejon Pass, California
This map is one of a set that shows the lines of inferred most recent movements on the San Andreas fault; it was compiled primarily to provide information for those concerned with land use and development on or near the fault. The mapped lines mark suspected displacement of the ground surface by rupture or creep along the fault.

Preliminary report on the geology of San Nicolas Island, California
The U. S. Geological Survey, at the request of the Director of Naval Petroleum Reserves, undertook a geologic investigation of San Nicolas Island, Ventura County California, in the spring of 1955. This preliminary report summarizes present knowledge concerning the general stratigraphy and structure of the island. Additional surface and underwater geologic studies are needed to further differentiate lithologic units within the complexly faulted Eocene sequence and to obtain additional data concerning the northwestward extension of the general anticlinal structure of the island.
