Limestone and shale facies of the Grant Lake Formation (Upper Ordovician; Katian; Maysvillian) are well exposed in the Cincinnati Arch of southern Ohio and north central Kentucky, and highly fossiliferous. These rocks also document gradual change in lithofacies and biofacies from offshore, nodular, phosphatic, brachiopod-rich limestones and marls to very shallow olive gray platy, laminated dolostones with desiccation cracks and sparse ostracodes, southward along a gently sloping ramp. This study uses facies analysis in outcrop to determine paleoenvironmental parameters, particularly those related to water depth (e.g., position of the photic zone and shoreline, and environmental energy). Within tightly a correlated stratigraphic interval (Mount Auburn/Terrill Mbrs.), we document the occurrence of paleoenvironmental indicators, including desiccation cracks, and light-depth indicators, such as red and green algal fossils, and oncolites.
