An former U occurrence/claim/mine located in sec. 30, T25N, R23E, G&SRM, 7.1 km (4.4 miles) NNE of Bidahochi, on the southern rim of Red Clay Mesa.

Mineralization is a finely disseminated ore body 45.72 meters long hosted in siltstone, sandstone, limestone of the Upper member of the Tertiary Bidahochi Formation, shale and tuff with chert and evaporites. Ore-grade rock occurs where the beds above an unconformity are sharply flexed. The identity of the U mineral is not apparent either megascopically or petrographically. Some copper mineralization is present. The beds are tilted toward the center of the diatreme. Associated rocks include Pliocene basalt. Local rocks include rocks of the Glen Canyon Group.

Production statistics: Year: 1959 (period = 1954-1959): 192 tons of ore at ^0.15% U3O8; 0.04% V2O5; and 0.75-1.00% P2O5 (makes alkaline leach difficult).

Workings include surface and underground openings comprised of a rim cut and a short adit on the SE rim of the diatreme.

2.588 - 5.333 Ma

ID: 3187166
Cenozoic sedimentary rocks

Age: Pliocene (2.588 - 5.333 Ma)

Lithology: Sedimentary rocks

Reference: Chorlton, L.B. Generalized geology of the world: bedrock domains and major faults in GIS format: a small-scale world geology map with an extended geological attribute database. doi: 10.4095/223767. Geological Survey of Canada, Open File 5529. [154]

5.333 - 23.03 Ma

ID: 3379965
Volcanic-crater sedimentary rocks

Age: Miocene (5.333 - 23.03 Ma)

Description: Commonly deposited within circular maar crater-vent depressions that display inward-dipping stratified pyroclastic and surge deposits interbedded with lacustrine sedimentary deposits. Consists of undivided epiclastic and lacustrine volcanic and fluvial sedimentary rocks of gray, light-yellow, and tan to white claystone, thin-bedded calcareous siltstone and sandstone, globular or bedded travertine, and gypsum interbedded with interbedded pyroclastic and mafic gray tuff and white ash. Bedded ash and tuffaceous conglomerate and sandstone deposits are moderately well sorted and commonly show intense soft-sediment deformation. Within “Coliseum” diatreme between Indian Wells and Dilkon (Na Ah Tee Canyon 7.5ʹ quadrangle; see also, fig. 1), 1-m (3-ft) thick sandy sediments contain fish fossils (Uyeno and Miller, 1965) that may suggest an environmental-sedimentary connection to the upper Bidahochi Formation north and northeast of quadrangle. Fossil algae and plant fragments are tentatively identified in other nearby maar volcanic-crater sediments. Thickness, 0.5 to 36+ m (1 to 120+ ft)

Comments: Volcanic rocks of Hopi Buttes (Tsezhin Bii) Volcanic Field (Miocene)—Unit was originally defined as the middle volcanic member of the Bidahochi Formation (Repenning and Irwin, 1954; Shoemaker and others, 1957, 1962); however, we herein redefine them as the volcanic rocks of Hopi Buttes Volcanic Field because it forms a mappable sequence of volcanic rocks that intertongues with deposits of the lower Bidahochi Formation (Tbl) of Miocene age near White Cone Peak northeast of quadrangle and in northeast quarter of quadrangle (sheet 2)

Toarcian - Norian
174.1 - 227 Ma

ID: 2976883
Glen Canyon Group

Age: Mesozoic (174.1 - 227 Ma)

Stratigraphic Name: Navajo Sandstone; Kayenta Formation; Moenave Formation

Description: Conspicuous red, cross-bedded Wingate Sandstone and the conspicuously cross-bedded, eolian, red to buff Navajo Sandstone form prominent cliffs in northern Arizona. These two sandstone units are separated by variably colored siltstone, silty sandstone, and sandstone of the Kayenta and Moenave Formations. (180-210 Ma)
