DIASTROPHIC RECORD 
The Neocene diastrophic record in California has been more 
or less studied by all of the writers who have attempted the 
problems of correlation. Naturally there is not entire harmony 
in the conclusions of all, but all agree as to the main facts. 
Dr. Fairbanks summarized much of the information current 
at the time of his writing in a paper entitled Oscillations of 
the California Coast,’ though considerable additional inform- 
ation has since been developed. The conclusions as to the 
diastrophic record reached in the present study of the Temblor 
basin may be more concisely presented graphically in the 
accompanying diagram. 
While some of the oscillations portrayed may be more or 
less local, they nevertheless show a tendency toward physical 
change that may be wide-spread, though not universal or 
uniform, within a given region. Furthermore, it may be 
stated that the oscillations here delineated do not include all 
that have recently been proposed by certain writers ambitious 
to cause a stir. 
It is believed that the conclusions of this paper, however, 
are in harmony with those of Dr. Smith set forth in the paper 
before referred to and quoted. But it is not designed to carry 
the subject farther at the present time. 
CONCLUSIONS 
The more important conclusions which may be drawn from 
the statements of the preceding pages are briefly summarized 
in the following paragraphs. 
The Neocene deposits of the Kern River area show a sur- 
prising lack of development when contrasted with contempor- 
aneous deposits in the Mt. Diablo Range. 
The comparatively small aggregate thickness of the series 
is partly explained by the fact that they do not contain all 
of the members of the generally accepted column of the Cali- 
fornia Neocene, or even all that have been recognized in the 
Mt. Diablo Range, which admittedly holds all that are most 
characteristic.
