Yeats (1965) deduced that the formation represents sediments deposited on the shelf and slope of the Pliocene Ventura Basin. The approximately 110 meter section of San Diego Formation exposed at Pacific Beach (Text-fig. 11) consists of a gently dipping sequence of highly fossihferous conglomerates, sands, and silty sands deposited in an outer shelf environment. This formation has traditionally been assigned a middle Pliocene age (Hertlein and Grant, 1944; Oakeshott, Jennings, and Turner, 1954), however, Allison (1964) recently placed at least part of the formation within the early Pleistocene. In addition to the sections and spot samples listed above, frequent reference is made to the 925 meter section of Miocene to lower Pleistocene sediments exposed at Newport Mesa (Text-fig. 1) described in earlier reports (Ingle, 1962, 1963a).
