Marion Peak Quadrangle, Fresno County, California; analytic data

Abstract

The Marion Peak 15-minute Quadrangle 36 degrees 45'-37 degrees 00' north latitude 118 degrees 30'-45' west longitude is underlain over 95 percent of its area by granitic rocks. This report documents major element chemical analyses of 30 samples and modal mineral analyses of 178 samples of granitic rocks. Specific gravity and magnetic susceptibility analyses are also included. The estimated average granitic rock in the quadrangle contains 69.2 weight percent SiO sub 2 .
