A bentonite occurrence/mine located in the SE¼SE¼NE¼ sec. 6, T21N, R28E, G&SRM, 7.5 km (4.7 miles) WNW of Sanders. The USGS MRDS database stated accuracy for this locality is 100 meters.

Mineralization is bentonite hosted in altered Pliocene tuff of the Bidahochi Formation. The bentonite ranges in thickness from 3 to 5 feet and up to 9 feet. It is chiefly calcium montmorillonite and contains only minor quantities of quartz and feldspar impurities. Local rocks include Pliocene to middle Miocene deposits.

Workings include mostly surface strip mining methods. Thick overburden has made strip mining less favorable.

ID: 2780990
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.
