- Stratigraphy and deposition of the Price Formation coals in Montgomery and Pulaski Counties, VirginiaBrown, K. Elizabeth (Virginia Polytechnic Institute and State University, 1983)The conclusion of this investigation, based on field mapping and measured sections, is the Price Formation was deposited on a high-energy shoreline. Sediments for the shoreline were initially transported from a northern deltaic source. The Cloyd Conglomerate Member represents offshore barrier bars, while the Lower Price unit was deposited in a lagoon behind the bars. At the top of the Lower Price unit, the "marker bed" sandstone includes sedimentary features of marine and fluvial origin. This sandstone is interpreted as a delta-front sand, reworked from distributary mouth bars. The Langhorn and Merrimac coal seams were deposited in swamps formed across the sandstone.
