Geology of a Portion of the Ravenna Quadrangle, Los Angeles County


Cowie, Roger Harrison (1938) Geology of a Portion of the Ravenna Quadrangle, Los Angeles County. Bachelor's thesis, California Institute of Technology. doi:10.7907/PR0E-MD33.


The area investigated contains a section of coarse fanglomerates and basic lavas of middle Tertiary age. It is, as far as known, unfossiliferous. The sediments have been tilted so that they dip in general southwest. Underlying the sediments on the north is a quartz-syenite basement rock. Faulted up on the south is an anorthosite basement. There is a prominent fault with several thousand feet of strike-slip displacement trending NE-SW through the center of the area. There are a number of short faults and steeply plunging open folds which trend in general NE-SW.
