The Brownsport Group is a geologic group in Tennessee. It preserves fossils dating back to the Silurian period.
The Nolichucky Formation is a geologic formation in Virginia and Tennessee. It preserves fossils dating back to the Cambrian period.
The Moccasin Formation is a geologic formation in Virginia and Tennessee. It preserves fossils dating back to the Ordovician period.
The Bowen Formation is an Ordovician-age geological formation in the Appalachian region of the eastern United States. It occupies a thin stratigraphic range between the Wardell and Witten formations in some areas of southwest Virginia and northeast Tennessee. It is particularly well-exposed in Tazewell County, Virginia. Unlike its encompassing strata, the Bowen Formation is mostly calcareous sandstone and mudrock rather than limestone. The thicker upper part of the formation is composed of layered red mudrock which is replete with mudcracks. The thinner lower part, which is not always preserved, is a coarser unit of dark grey stratified sandstone which weathers to a rusty-brown color. Fossils are rare, restricted to stromatolites and Tetradium fibratum.
