A clay occurrence/former mine located in the NW¼ sec. 25 & 26, T21N, R29E, G&SRM, 9.1 km (5.7 miles) ESE of Sanders, 10.3 km (6.4 miles) SSW of Houck and 13.1 km (8.1 miles) SSW of Allentown, on private land. First production occurred in 1924. Owned by the Filtrol Corporation, California. The USGS MRDS database stated accuracy for this locality is 500 meters.

Mineralization is clay in Pliocene latite ash in the Bidahochi Formation. a 4 foot thick bentonite bed is comprised chiefly of calcium montmorillonite and contains only minor quartz and feldspar impurities. The bentonite is nearly pure calcium montmorillonite with a high crystallinity and a large surface area that produces extraordinary sorptive properties. Local alteration involves vitric latite ash. Local rocks include Pliocene to middle Miocene deposits.

Regional geologic structures include the Defiance Uplift.

Production was considerable. The average overburden of the mined deposits was nearly 100 feet in 1987 and stripping costs were high.

ID: 2919112
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)

Comments: In dissected basins of southeast and central Arizona Original map source: Arizona Geological Survey, DI-8 Geologic Map of Arizona, Digital Spatial data for the Geologic Map of Arizona, v. 3.0, edited by S.M.
