Pagina 154 - Instead of the numerous subdivisions recognized by most stratigraphers, there are, in fact, only two major faunal units in the Miocene of California: a lower, including all the faunas up through the Monterey; and an upper, including the San Pablo, Santa Margarita, and Etchegoin faunas. The division line between them corresponds to the period of erogenic activity that came on at the end of the Monterey epoch.

Pagina 116 - McKittrick series." The opinion has been unequivocally expressed1 that in the Coalinga field the real source of the petroleum is in the Eocene shales underlying the Neocene, and that migration of the petroleum upward through the strata has brought it into its present repositories in the Neocene oil measures. That petroleum, in some parts of the Mt. Diablo Range and elsewhere, has originated in the Eocene cannot be denied, and it is also now found there in many places. But to conclude that all or...

Pagina 40 - Vaquero" and its application to any strata outside of the type locality, it has no logical standing, and its claim upon accepted usage rests only upon assumption. south, while in the Salinas valley and elsewhere beds that have been generally called San Pablo and otherwise correlated with it, are undoubtedly more closely related to the Coalinga. This is true of the Santa Margarita beds described by Fairbanks,1 which also occur at La Panza Springs, Nacimiento river, and on the Estrella and San Lorenzo...
Pagina 29 - ... miles northeast of Coalinga (NW. J sec. 1, T 19 S., R. 15 E.). A general description of the formation was given. Its upper limit was stated to be at the base of the fresh-water deposits in the vicinity of Tulare Lake and the Kettleman Hills, described as the Tulare formation. Mr. Anderson states that "one or two fossil horizons are to be recognized in the Etchegoin sands, one near their bottom and another some distance above.
Pagina 114 - Stratigraphically, the oil is not found in a single bed extending across the field, but in sandy beds more or less separated by clays and distributed through the oil-measures. The sandy beds and clays interleave, often forming an alternating series throughout the measures. As a rule, in the developed portion of the field the sands are thicker in the eastern part of the field and become thinner toward the west, and the clays are thicker on the western border and become thin and scattered toward the...
Pagina 277 - Wolf. Range — Northern California, and south along the Sierra Nevada. Now rare or extinct. The number of records (eg, Price, Zoe, 4, 1894, p. 331) and reports from the region specified carries conviction that a wolf of some form has occurred as above indicated. But lack of specimens brings doubt as to the race represented. Canis latrans lestes Merriam Mountain Coyote Original description — Canis lestes Merriam, Proc.
Pagina 29 - San Joaquin Clays." The sands of this series are commonly coarse in texture and often pebbly, forming beds of conglomerate. Many of the pebbles and sand grains are jet black in color, and mingled with these is a kaolin-like matter, perhaps a decomposition product from volcanic ash. The gray-blue color which is so noticeable in these beds may be due to these ingredients and to their manner of mixture. This color has not been noticed in either of the other series and has generally been found to be...
