Battiest Chert Member of Tenmile Creek Formation of Stanley group. Proposed for chert member in middle part of formation. Battiest chert member was named †Smithville chert lentil [not incl. in this lexicon; see USGS Bull. 896, p. 2014] by Miser and Honess, 1927 (Oklahoma Geol.

Where best exposed, west of Battiest, member is 15 feet thick and consists of 3-inch beds of dark cherty siliceous shale interbedded with black siliceous shale; one 6-inch bed of black chert is cut by veins of milky quartz. Near Beachton (in type area of Honess' and Miser's Smithville chert) member consists of 15 feet of blue-black chert and siliceous shale which is poorly exposed in series of tight folds trending east-west. Age is Late Mississippian (Meramec).
