Abstract

The segment of the South Fork thrust in the Belknap ranch area contains rocks representative of the Upper Jurassic, Lower Cretaceous and Upper Cretaceous. The thrust plate occupies 75 percent of the mapped area. Approximately 3,500 feet of predominantly marine rocks comprise the detachment thrust and about 15 percent of the exposed rocks of the thrust plate is sandstone and conglomerate. All the rock units present in the thrust plate crop out beyond the edge of the over-riding mass except the Sundance and Morrison formations. Approximately 4,600 feet of geologic section is exposed of drilled in the mapped area. The rocks range in age from Pennsylvanian to Recent.
