Bloomfield limestone is treated as member of Anderson cyclothem (new) of Conemaugh series. Underlies Anderson clay member; overlies Bakerstown shale and (or) sandstone member. According to Waage (1950: MD Dept. Geology, Mines and Water Resources Bull. 9), Hennen and Reger (1914) named an equivalent limestone in Preston Co., WV, the Albright limestone. Thus, Albright has precedence over Bloomfield. Recommended that Albright replace Bloomfield if and when positive correlation is determined.
