Pg. 297-300. Strawberry Creek Formation. Name proposed for 1 of 6 formations of the McCoy Creek Group (new). Previously included in Prospect Mountain Quartzite (restricted). Consists of quartzites, argillites, and metasiltstones. Described as brown-weathering, olive-drab, gray, quartzose, silty, in part phyllitic, very fine-grained argillites and metasiltstones alternating with thin, light- and medium-gray, rusty-brown weathering, fine-grained quartzite. Some of the impure quartzites are schistose. Quartzite predominates in some sections whereas argillite and metasiltite predominate in other sections. Thickness about 750 feet near head of Strawberry Creek; is a slope-former between two cliff-forming quartzites. Overlies Willard Creek Quartzite (new) of McCoy Creek Group; underlies Shingle Creek Conglomeratic Quartzite (new) of McCoy Creek Group. Age is late Precambrian. Report includes geologic map.
Type area: in vicinity of Strawberry Peak, northern part of southern Snake Range. Where best exposed [= type locality] on north side of upper Strawberry and upper Willard Creeks where its rocks are altered by contact metamorphism. Named from Strawberry Creek, southern Snake Range, White Pine Co., northeastern NV (Great Basin region).
