Mississippian 323.2 - 358.9 Ma ID: 1824284 | Renault Limestone Age: Mississippian (323.2 - 358.9 Ma) Description: Limestone, light-gray, medium-crystalline, oolitic (ooids 1/4 to 1/2 mm in diameter common); upper few feet is medium gray, argillaceous, and silty with some disseminated pyrite; locally contains some greenish gray calcareous shale, and, in some places, about 5 feet of dense, greenish-gray dolomite near base. \nShale, greenish-gray to gray, calcareous, very fossiliferous; clay is dominantly illite with some kaolinite. Includes a few 1- to 2-foot beds of limestone near top and bottom; limestone is medium to dark gray, very fossiliferous; small brachiopods, horn corals, and Pentremites sp. are common. \nLimestone, medium-gray, finely crystalline, oolitic rarely, argillaceous; basal 3 to 5 feet is very sandy or silty; rarely a conglomerate as much as 1/2 foot thick occurs in this clastic zone; conglomerate is composed of limestone pebbles in a silty or very fine sand matrix.
