just north of Pajaro River. He recognized a "Miocene Series" 

 lying uneonformably above the Franciscan and unconformably 

 below the San Pablo. He divided it "on lithological grounds" 

 into a lower portion chiefly sandstones (1500 feet), which he 

 said is "probably of Lower Miocene age," and an upper, chiefly 

 bituminous shales with occasional limestones (3000 feet), called 

 "Monterey Shale." The former is described as "very similar 

 t<> the Temblor beds of the Monte Diablo range described by 

 P. M. Anderson." "There are several thick beds of siliceous 

 shale in the terrane which has tentatively been called Lower 

 Miocene, but the presence of large amounts of sandstone, clay 

 shale and conglomerate distinguish it from the overlying Mon- 

 terey." The upper shales ("Monterey shale") are said to lie 

 conformably on the lower beds, and at two localities overlap the 

 latter (as is normal for a conformable series) and lie directly 

 on diorite or Franciscan sandstone. It is evident that the rela- 

 tions described are typical of the Monterey series throughout 

 most of the coastal part of the province. 



Kern River Region, F. M. Anderson, 1911. — In November, 

 1911, F. M. Anderson 75 published "The Neocene Deposits of 

 Kern River, California, and the Temblor basin." He describes 

 the representatives of the Monterey Series in the Kern region, 

 on the east side of the southern San Joaquin Valley, under the 

 heading "Temblor 70 Group, which he divides into a "basal mem- 

 ber," 350-600 feet thick, and an "upper member," 1260 feet 

 thick. He described the basal member as essentially sandy. 

 "Some of the lower beds consist largely of volcanic ash, pumice, 

 and sand. . . . Basal conglomerates are visible in only a few 

 places, but a stratum of at least 50 feet is exposed at one point 

 north of the Kern River" (pp. 90-91). 



The upper member "contains a smaller percentage of sand 

 and other detrital matter, and a greater percentage of organic 

 material than any other portion of the Neocene. And of the 

 detritus present a great portion is of clay and shaly matter."

 ™ Anderson renewed his attack on the legitimacy of the term Vaqueros 

 as explained above, and insists on the use of Temblor. Footnote, p. 106.
