摘要
The copper deposits in the mid-lower reaches of the Changjiang River consist mainly of porphyry, skarn and massive sulphide deposits. According to the geological background, the types of ore deposits and the mineralization, the metallogenic model of the copper deposits is discussed. It is pointed out that the ore-forming hydrother-mal fluids came mainly from magmatic water and were related to the intermediate-acid intrusions, and that the formation of skarn and massive sulphide deposits coincided with the mineralization of porphyry deposits.
