Summary:
Named for exposures at Oxyoke Canyon. Type section in Oxyoke Canyon on southwestern slope of Beacon Peak [sec 16, T18N, R54E, Pinto Summit 15' quad, White Pine Co, NV]. Is next to lowest member of Nevada formation (Merriam, 1940). Exposed in southern end of Diamond Mountains (Hornitos Cone, Silvarado, Alhambra Hills), also in linear band from Black Point to beyond Phillipsburg mine, and small exposure at eastern base of Newark Mountain near Gimme mine. Composed of light-olive-gray thick-bedded sandstone or quartzite that commonly weathers to shades of brown. Beds are commonly several feet thick and exhibit cross-bedding. Thickness 400 to 450 ft. In mapping highest sandstone bed or lowest dolomite bed has been taken as boundary. Gradational contacts with underlying Beacon Peak dolomite member (new) and overlying Sentinel Mountain dolomite member (new). Age is Early and Middle Devonian.

Summary:
Western tongue of Oxyoke Canyon Formation recognized in Sulphur Spring Range where it conformably overlies Sadler Ranch Formation (new) and underlies Sentinel Mountain Dolomite. In "transitional area" which includes Modoc Peak, Sulphur Spring Range and Pinyon Range, unit is informally divided into upper coarse crystalline member and lower quartzose member. The lower quartzose member intertongues with the Sadler Ranch Formation.
