Summary
[edit]DescriptionFossiliferous limestone (Boggs Limestone, middle Pottsville Group, lower Middle Pennsylvanian; outcrop spanning Blunt Run, northern Muskingum County, eastern Ohio, USA) (15559339658).jpg |
Fossiliferous limestone from the Pennsylvanian of eastern Ohio, USA. (5.1 cm across at the base) The Pottsville Group is a Pennsylvanian-aged cyclothemic succession in eastern Ohio that contains nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?). The Boggs Limestone is a relatively thin stratigraphic interval. It typically consists of marine fossiliferous limestones, dominated by brachiopods and crinoid ossicles. Significant lateral and vertical lithologic variation is present - the Boggs interval ranges from being a fossiliferous limestone to an intraclastic limestone to a ferruginous chert to a dolostone. In places, it has a relatively high component of disseminated pyrite. In other places, it is relatively rich in black manganese oxide(s). Minerals observed in the Boggs Limestone interval: calcite, dolomite, glauconite, goethite, gypsum, limonite, pyrite, sphalerite, turgite, vivianite, wad. Stratigraphy: Boggs Limestone, middle Pottsville Group, lower Atokan Stage, lower Middle Pennsylvanian Locality: outcrop spanning Blunt Run, just west of the Muskingum River, ~6 miles north of Zanesville, eastern Muskingum Township, northern Muskingum County, eastern Ohio, USA |
