Geologic Map Symbol Table F1: Offset Project Area Geology Geologic age Formation Rock Type Description Acres Osv Ordovician Sevier Shale shale, limestone OCk Ordovician to Cambrian Knox Group Ojb Ordovician Jonesboro Limestone dolostone (dolomite), limestone limestone, dolostone (dolomite) Calcareous, bluishgray shale, weathers yellowish-brown; with thin gray limestone layers; sand stone, siltstone, and locally conglomerate to the east. Thickness 2,000 to 7,000 feet. Siliceous, wellbedded dolomite and magnesian limestone in the central and northwest belts of the Valley. To the southeast, much dark limestone is present and the rocks are only sparsely cherty. Thickness about 3,000 feet. Dark bluish-gray, ribboned (silt and dolomite) limestone; numerous interbeds of darkgray dolo mite; quartz sandstone at base. Erosional unconformity at top. Thickness about 2,000 feet. 21,745 3,
