Summary[edit]
DescriptionSilica Formation over Dundee Limestone (Middle Devonian; Lafarge Paulding Quarry, near Paulding, Ohio, USA) 37 (48907003656).jpg |
This is the Paulding Quarry in far-northwestern Ohio. The quarry opened in 1949 and the rocks are used to make cement on-site. The target unit is the Middle Devonian Dundee Limestone. The upper quarry wall seen here consists of interbedded fossiliferous limestones and shales of the Middle Devonian Silica Formation. The fossils are typical mid-Paleozoic marine invertebrates such as brachiopods, bryozoans, corals, crinoids, and trilobites. Below the Silica is the Dundee Limestone, which lacks interbedded shales. Locality: Paulding Quarry (= Lafarge Paulding Quarry), north-northwest of the town of Paulding, northern Paulding County, northwestern Ohio, USA (41° 10' 57.96" North latitude, 84° 37' 21.23" West longitude) |
