A former U-V-Mo occurrence/mine located in approximate sec. 27 and 3, 4, T41N, R23E, G&SRM, 1.5 km (1.0 mile) SSE of Yazzi Mesa (coordinates of record) and 10.3 km (6.4 miles) NNW of Dennehotso (town). Now part of the Monument No. 2 Supplement.

Mineralization is tyuyamunite, montroseite and carnotite in lenticular ore pods in the Permian De Chelly sandstone of the Shinarump Conglomerate Member of the Chinle Formation and the Salt Wash member of the Morrison formation. Deposits occur in the bottom of a paleostream channel, usually with carbonaceous debris. Mineralization occurs for 7 feet into the De Chelly sandstone. A replacement deposit. Local rocks include Permian to Pennsylvanian sedimentary rocks.

Production was 438 tons of ore @ 0.31% U3O8; 1.23% V2O5 (1955-1957).

Mined out.

Regional Geology

This geological map and associated information on rock units at or nearby to the coordinates given for this locality is based on relatively small scale geological maps provided by various national Geological Surveys. This does not necessarily represent the complete geology at this locality but it gives a background for the region in which it is found.

Early Jurassic - Late Triassic
174.1 - 237 Ma



ID: 3185972
Mesozoic sedimentary rocks

Age: Mesozoic (174.1 - 237 Ma)

Lithology: Sandstone-conglomerate

Kungurian - Moscovian
272.95 - 315.2 Ma



ID: 2778803
Permian to Pennsylvanian sedimentary rocks

Age: Paleozoic (272.95 - 315.2 Ma)

Stratigraphic Name: Hermit Formation; Supai Group; Schnebly Hill Formation; Naco Group

Description: Interbedded sandstone, shale, and limestone usually characterized by ledgy outcrops. Orange to reddish sandstone forms cliffs near Sedona. This unit includes Supai Group and Hermit Shale in northern Arizona and Naco Group in southern Arizona. It was deposited in coastal-plain to shallow-marine settings during time of variable and changing sea level. Rocks of this map unit in southern Arizona may be in part equivalent to Permian rocks of map unit P in central and northern Arizona. (280-310 Ma)
