Comments In western Berks County, near Frystown and Wintersville, where fetid barite float occurs. The barite appears to be constrained to two east-west-trending black shale belts in the Cambrian-Ordovician Hamburg sequence.
Cover thickness and description Outcrop limited to roadcuts, stream banks, and borrow pits, but float (eluvium and colluvium) is relatively abundant.
