Connecticut Mine was a western expansion of the Delaware
Fissure and like Delaware mine, the Connecticut mine produced very little
copper but somewhat adundant in datolites. The datolites from Connecticut
are white sometimes with red dots and some are more orangish due to higher
concentration of reddish to orange dots. The colorful datolites from Connecticut
often have been passed as coming from Delaware Mine where orange datolites
are quite rare in Delaware Mine.
