Summary:

Pg. 296, 297, 298-299 (pl. 1). Willard Creek Quartzite. Name proposed for 1 of 6 units in the McCoy Creek Group (new). Is a massive cliff-forming unit about 500 feet thick. Consists of white to gray, vitreous quartzite with some micaceous, phyllitic partings. Quartzite beds range from 1 to 2 feet thick, weather brown to gray and blocky; locally, exhibit small-scale cross-bedding. Contains some gritty and pebbly areas; pebbles are well-rounded quartz pebbles. Underlies Strawberry Creek Formation (new) of McCoy Creek Group. Overlies unnamed brownish-weathering, weakly metamorphosed, quartzite formation at base of McCoy Creek Group. Age is late Precambrian. Report includes geologic map.
Type locality: north of Strawberry Pass and north of Strawberry Creek in the southern Snake Range, White Pine Co., NV (Great Basin region). Well exposed on north side of upper Strawberry and upper Willard Creeks in the southern Snake Range. Named from Willard Creek, southern Snake Range, White Pine Co., northeastern NV (Great Basin region).
