|Location and accuracy||The Mount Sorensen occurrences cover an approximately 4-square-mile area centered about 3 miles west of Mount Sorensen, in section 22, T. 2 N., R. 23 E., of the Fairbanks Meridian.|
Geologic descriptionMount Sorensen is the largest ultramafic body in the Eagle quadrangle, and it is composed of partially serpentinized peridotite, dunite, and harzburgite (Foster and Keith, 1974). As much as 1 percent chromite is present in some of the least serpentinized rocks. Serpentinized dunite and harzburgite at Mount Sorensen were assayed using fire assay and spectrographic methods; they contain as much as 0.01 ppm platinum and up to 0.01 ppm palladium (Keith and Foster, 1973).
