The Chengchao iron deposit, the largest high-grade skarn iron deposit in southeastern Hubei Province, contains considerable amounts of magnetite and by-product anhydrite. To obtain better understanding of the ore-formation process, this study carried out He-Ar-S-Pb multi-isotopic analyses on the pyrites formed during two stages of mineralization.

The value of the ore depends to a great extent on the chemical composition, the value falling sharply with the decrease in manganese content below a certain minimum; impurities like iron, phosphorus, silica and alumina should not exceed certain limits. Therefore, the correct analysis of the elements is required.
