Summary:

Named Cooney Canyon Member, upper member of Cooney Tuff. Is a rhyolitic to quartz latitic ash-flow tuff, about 200 m thick in Cooney Canyon, and 400 to 500 m thick on north side of Whitewater Creek. Consists of multiple simple and compound cooling units. Tuff vary from partially welded to densely welded. Some cooling units separated by a few meters of volcaniclastic sandstone. Tuff units are petrographically variable, 25 to 45 percent phenocrysts, 1 to 3 m diameter of oligoclase-andesite, minor biotite, and opaque oxide, and rare clinopyroxene, zircon, and oxyhornblende in a devitrified cryptocrystalline matrix. Overlies Whitewater Creek Member of Cooney Tuff; underlies various unnamed volcanic rocks. Replaces upper quartz latitic member of Cooney Tuff of Ratte and Finnell (1978). Age is Oligocene, based on K-Ar (on biotite) age of 32 +/- 1.5 m.y.
Type section in sec. 20, T. 10 S., R. 19 W. Named from Cooney Canyon, Mogollon quadrangle, Catron Co., NM, [Basin-and-Range provinvce].
