Summary:

Pg. 196 (fig. 1), 204-205 (fig. 3), 212-213, 217 (fig. 4), 224-230. Temblor stage. Discussion of Miocene of Caliente Range and environs. Marine Miocene is a transgressive series, essentially conformable basinward, but revealing, strandward, the occurrence of two oscillations which respectively inaugurate and divide its upper third. It comprises three nearly equal divisions, Vaqueros, Temblor, and Monterey stages, which approximate lower, middle, and upper Miocene. Each of these has more or less distinctive epeiorgenic history, fauna, and average physical aspect. At Caliente Mountain, a homoclinal section exposes about 1,100 feet of upper Oligocene(?), 4,500 feet of Vaqueros, 4,700 feet of Temblor, and 4,600 feet of Monterey strata.

Summary:

Pg. 25-60. Correlation chart of Kern River area shows Temblor comprises (ascending) Pyramid Hill sand, Freeman-Jewett silts, Olcese sand, and Round Mountain silt members. Principal cartographic unit in area is Round Mountain silt member; less widespread are Olcese sand and the Freeman-Jewett silt. Additional members of Temblor underlie the area but outcrop beyond borders of map.

Summary:

Pg. 213-215, 226 (fig. 5). Temblor group, in San Benito quadrangle, is represented by three mappable units: lower sandstone, 100 to 500 feet thick; shale in middle of section, 300 to 1,000 feet thick; and upper sandstone, 400 feet thick. They are exposed along axis of Butts Ranch syncline and are youngest rocks affected by the folding. Disconformably overlies Kreyenhagen shale. Age is middle Miocene.

Summary:

Pg. 22 (fig. 4), 35-36, pl. 1. Temblor formation. Fine-grained yellowish sandstone; cross-bedded, fossiliferous interbedded sandstone and pebbly sandstone, 50 to 100 feet; and basal conglomerate. Total thickness 500 to 1,000 feet; continuous section not measured. Exposed in small areas north and east of Calaveras Reservoir, Santa Clara and Alameda Counties, western California. Unconformably overlies Jurassic Franciscan formation. Grades upward into Monterey shale; where Monterey is absent, unconformably underlies Briones sandstone. Formation is limited on west by fault of the Calaveras system. [Age is late Miocene.]
[Misprint (US geologic names lexicon, USGS Bull. 1200, p. 3846): the Temblor unconformably overlies Franciscan, not conformably overlies.]
