Facies variations in the Woocalla Formation and their relation to base metal mineralization.
Metal sulphides occurring in dolomitic mud and silt facies (Sweet Nell type deposits) were probably deposited in a supratidal environment, where the dolomitic shale facies with Cu mineralization probably originated closer inshore, while Pb, Zn...-
