Brines from the Whirlpool Sandstone (Silurian) in Morgan, Muskingum, and Ashtubula counties are enriched in Ca and Sr, but depleted in Na, K, and Mg relative to sea water. This result indicates that chemical reactions such as dolomitization and secondary feldspar formation have occurred. The brines of the Whirlpool Sandstone are resolvable into three components: meteoric water, Na-enriched brine and Ca-enriched brine. One brine sample was discovered to be anomalous. It appears to have originated from the Rose Run Formation located 1,500 feet below the Whirlpool Sandstone. The anomaly implies the existence of a vertical fault or fracture in Morgan County.
