An U-Pumice occurrence located in the SE¼SE¼ sec. 12, T23N, R21E, G&SRM, 0.9 km (0.6 mile) SSE of Bidahochi (town), 0.2 miles SE of Bidahochi Trading Post.

Mineralization is a disseminated ore body hosted in Pliocene shale, siltstone and limestone of the Upper Member Of Tertiary Bidahochi Formation. Extremely finely disseminated uranium in limestone and laminated siltstone and shale of the Bidahochi Formation associated with a diatreme feature also containing bedded tuff, evaporites and chert. Local rocks include rocks of the Glen Canyon Group. The Arizona Department of Mineral Resources locates volcanic ash in sec. 11, T23N, R22E.

Analysis test results: 0.01% to 0.2% U3O8.

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: 3381157
Mixed monchiquite and basanite flows and tuff deposits, undivided

Age: Miocene (5.333 - 23.03 Ma)

Description: Gray or brown monchiquite and basanite flows interbedded with mafic tuff-and-ash deposits. Contains abundant phenocrysts and glomerocrysts of clinopyroxene, olivine, and phlogopite. Includes several mixed flows and pyroclastic deposits from multiple volcanic eruptions in north half of Hopi Buttes area (sheet 2). Thickness, 9 to 146+ m (30 to 480+ 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)

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)
