长江中下游地区铜多金属矿床成矿预测研究

Metallogenic Prediction of Copper Polymetallic Deposits in the Middle and Lower of Yangtze River

长江中下游地区是我国铜多金属矿床分布的重要基地,江西九江城门山铜多金属矿床在特有的地理环境下,形成了以钼为核心的矽卡岩型铜矿、斑岩铜矿、块状硫化物铜矿"三位一体"的组合分布规律。研究表明,该区域的铜多矿床形成与燕山期深源中酸性岩浆活动有着密切的关系,而赋矿围岩的物理化学性质及基底类型是矿床形成的外部条件。

The middle and lower reaches of the Yangtze River region is an important base of copper polymetallic deposit in China.Menshan copper polymetallic deposit in Jiujiang city will be the unique geographic environment to formwith a core of molybdenum skarn type copper deposits and porphyry copper deposits,including massive sulfide copper distribution regularity of the combination of the ＂trinity＂.Researches show that the area of copper ore deposit formation is of deep source intermediate-acid magmatic activity in Yanshan period,which has close relations.The chemical and physical properties of ore rock and basal type are the external condition of ore deposit formation.
