An Ti-Zr-Th-U-REE occurrence located in the approximate E½ sec. 29, T33N, R23E, G&SRM, about 1.4 km (0.9 mile) ENE of Taasahdi Dzil (summit) (coordinates of record). The geographic coordinates presented are approximate to the center of the E½ of sec. 29.

Mineralization is a Ti-Zr-Th-U-REE deposit with a 6 inch thick black placer sand in the Toreva Formation, capping a small mesa. The deposit is composed of Ti-rich placer concentrate with U-bearing zircons and Th-bearing monazite. Caps a cliff-forming sandstone on the north side of an E-flowing tributary to Tah Chee Wash. Airborne anomaly.

Analysis test results: 10-30% TiO2.

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.

Santonian - Coniacian
83.6 - 89.8 Ma



ID: 2828851
Sedimentary rocks of the Late Cretaceous Mesaverde Group

Age: Late Cretaceous (83.6 - 89.8 Ma)

Stratigraphic Name: Mesaverde Group

Description: Gray to buff sandstone with interbedded shale and coal. These rocks, which are similar to slightly younger rocks that form Mesa Verde in southwestern Colorado, were deposited on the margin of a shallow sea. Rocks of this map unit host the only large coal deposits in Arizona. (84-88 Ma)
