Abstract: | 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 hydrothermal fluids came mainly from magmatic
water and were related to the intermediate-acid intrusions, and that the formation of skarn arid massive sulphide deposits
coincided with the mineralization of porphyry deposits.
