Summary:
Pg. 46, pl. 1. Belmont fanglomerate. Formal proposal of name. Composed of unsorted and generally massive limestone, sand and pebbles, chert pebbles, and locally quartzite and granitic debris. Drillhole near Monte Cristo penetrated 1,200 feet of gravel without encountering bedrock. Upper formational contact arbitrarily placed because no clearly defined boundary between fanglomerate and recent alluvium and reworked gravels was recognized. Overlies Lake Newark formation (new) or bedded gravels which possibly correlate with Lampson formation. Age is Pliocene and (or) Pleistocene.
Named from Belmont Canyon, White Pine mining district, White Pine Co., northeastern NV.
