Summary
[edit]DescriptionCrystalline vein in black mudshales (Sunbury Shale, Lower Mississippian; Tener Mountain roadcut, southern Ohio, USA) (39990138473).jpg |
Shale with vein in the Mississippian of Ohio, USA. The Sunbury Shale is a black mudshale succession in Ohio - it is the oldest fully Mississippian-aged unit in the state. It occurs above the Berea Sandstone and below the Cuyahoga Formation. The Sunbury essentially identical to the older Ohio Shale. Compared with the Ohio Shale, the Sunbury is considerably thinner. Sunbury outcrops are uncommon, but an extensive exposure is present at the Tener Mountain roadcut in southern Ohio. The unweathered rocks are black mudshales, but weathered material consists of medium- to light-colored chips. I have not observed fossils in the Sunbury at this site, but the literature refers to lingulid brachiopod fragments in the lower Sunbury. The brownish-weathering linear feature in the center of the picture is a crystalline-textured vein. It didn't bubble in acid, so it's not calcite. Samples are not noticeably heavy for their size, to it's unlikely to be barite. Stratigraphy: Sunbury Shale, Kinderhookian Stage, lower Lower Mississippian Locality: Tener Mountain ditchcut along the northwestern side of Rt. 32 (= Appalachian Highway), at the Rt. 32-Union Hill Road intersection, just southwest of the Adams County-Pike County line, far-northeastern Adams County, southern Ohio, USA (39° 01' 11.11" North latitude, 83° 16' 48.68" West longitude) |
