Pg. 951, pl. 9. Acme dolomite in Blaine formation of Double Mountain group. Above Mangum dolomite the first prominent dolomite is a series of several beds, 1 to 6 feet thick, which has been called the Acme, from its type exposure in Hardeman County, where thick beds of gypsum below the dolomite are mined. The Acme is traced southward to Stonewall County and may be correlated with reasonable certainty with McCaulley beds of Fisher County. It lies 64 feet above Mangum dolomite and 90 feet below Guthrie dolomite, all in Blaine formation. Age is Late Permian. See also [1932] entry under McCaulley dolomite.
Type exposure: [town of Acme] in Hardeman Co., TX.
