| Description |
Limestone in the Devonian of Ohio, USA. The Delaware Limestone is a significant carbonate unit in the Middle Devonian of central and northern Ohio. It's actually part of a much more widespread sheet of Devonian carbonates that extends from New York State to the Midwest. The Delaware Limestone represents deposition in a subtropical, shallow-water, carbonate platform environment. The rocks are principally micritic limestones, fossiliferous wackestones, and fossiliferous packstones. Fossils are typical Paleozoic shallow marine invertebrates. The thin-bedded Delaware Limestone is underlain by the thick-bedded Columbus Limestone (also Middle Devonian). The contact is a prominent disconformity (a type II sequence boundary). Biostratigraphic studies have shown that one conodont biozone is missing at the Columbus-Delaware contact in central Ohio, probably representing ~1 to 3 million years. The Delaware Limestone is overlain by soft gray clayshales of the Olentangy Shale (lower Upper Devonian). Stratigraphy: Delaware Limestone, Eifelian Stage, lower Middle Devonian Locality: creek cut along Lazarus Run, eastern side of Chapman Road, south of the town of Delaware, central Delaware County, central Ohio, USA (~40º 13’ 58.97” North latitude, ~83º 03’ 37.55” West longitude) |
