An U occurrence/group of claims located in the N-central sec. 32, T20N, R17E, G&SRM, on the edge of Ives Mesa. The geographic coordinates presented are approximate to the center of sec. 32. This locality is not listed in the USGS MRDS database.

Mineralization is an U deposit that occurs in 2 sandstone lenses or paleochannels in the Petrified Forest Member of the Chinle Formation. The ore body is at a depth of 50 feet and averages 4-5 feet thick. Lenses are separated by 20 feet stratigraphically, with both trending ENE, and are superimposed.

Workings include underground openings comprised of 1 100 foot adit from the rim towards the ore body. 64 holes were drilled in 1955 for 8,200 feet.

Production was 49 tons of ore @ 0.03% U3O8; 0.17% V2O5 (1954) (reported from the Winslow No. 7).

Holocene

ID: 3374314
Eolian sand-sheet deposits

Age: Anthropocene (0 - 0.0117 Ma)

Description: Extensive sand-sheet deposits northeast and east of Little Colorado River Valley, especially in and along large tributary washes and over gently sloping terrain below Newberry, Ives, and Marcou Mesas. Forms thin sand-sheet deposits on alluvial fan slopes of various ages and on “Dilkon deposits” (QTdi) slopes in Hopi Buttes area. Commonly intertongues with surficial deposits (Qae, Qdp, Qdb); contacts are gradational in both lateral and vertical sense. Supports moderate growths of grass and small high-desert shrubs that help stabilize or trap accumulating deposits. Thickness, 0.3 to 4.5 m (1 to 15 ft)

Lithology: Sand

Gelasian - Burdigalian
1.806 - 20.44 Ma



ID: 2847471
Pliocene to middle Miocene deposits

Age: Cenozoic (1.806 - 20.44 Ma)

Description: Moderately to strongly consolidated conglomerate and sandstone deposited in basins during and after late Tertiary faulting. Includes lesser amounts of mudstone, siltstone, limestone, and gypsum. These deposits are generally light gray or tan. They commonly form high rounded hills and ridges in modern basins, and locally form prominent bluffs. Deposits of this unit are widely exposed in the dissected basins of southeastern and central Arizona. (2-16 Ma)
