GENERAL FEATURES OF THE STRUCTURE OF THE BEDROCK COMPLEX OF 

 THE SIERRA NEVADA 



BY GEORGE D. LOUDERBACK 



(Abstract) 



The lower western slope of the Sierra Nevada is characterized by remark- 

 able linear extent and comparative regularity of relatively thin belts of strata 

 of tbe "Bedrock Complex." The bearing of this on the interpretation of the 

 structure was pointed out. Criteria for judging the different types of folding 

 in a practically isoclinal complex were discussed, and the conclusion was ar- 

 rived at that the major structures of the "Bedrock Complex" are of a com- 

 paratively simple nature, much more simple than previously considered. The 

 probable nature of folding was indicated, and methods of testing hypothesis in 

 field proposed. 



Presented from notes, and illustrated by maps and diagrams. Dis- 

 cussion by Lawson, J. P. Smith, Merriam, and Clark.
