these beds to the Monterey rather than to the Vaqneros is evident. 



San Jose and Bit. Hamilton Quadrangles, Templeton, 1912. — 

 At the April, 1912. meeting of the Cordilleran Section of the 

 Geological Society of America E. C. Templeton presented a paper 

 on ' ' The General Geology of the San Jose and Mt. Hamilton 

 Quadrangles, " so in an abstract of which he says: 4 "The lowest 

 Miocene sandstone belongs to the Temblor phase of the Mon- 

 terey series and rests unconformably on the Franciscan. . . It 

 has an abundant fauna, typically Temblor. Its thickness is 

 about 1000 feet. Overlying it is the Monterey shale, hard, light- 

 colored, and siliceous, with a thickness of about 1200 feet. . . . 

 The Monterey shale is overlaid, apparently conformably, by a 

 thickness of about 3500 feet of sandstone with a typical Temblor 

 fauna, ' ' 



It is evident here that "Monterey shale" is used merely in 

 the sense of a depositional facies, and "Temblor" is used in a 

 faunal sense. The relative position of beds is instructive. 



Kirker Pass, Clark, 1912. — The Monterey section of Kirker 

 Pass, north of Mount Diablo, has recently been described by 

 Bruce Clark. 81 The fossils found in the upper part of the section 

 are referred to the upper Monterey.

GENERAL CONCLUSIONS 

 GENERAL DESCRIPTION OF MONTEREY SERIES 



Monterey Sediments 

 General Distribution. — The Monterey series (including such 

 local divisions as have been called Vaqneros, Monterey shale, 

 Modelo, Puente, Temblor, etc.) is a natural stratigraphic unit. 

 It represents a cycle of sedimentation in the geologic history of 

 the Pacific Coast, which has produced one of the most important 

 and widespread series of deposits in the California region. 82

 been more extensively studied there.
