已知矿床的主要类型有伟晶岩型矿床、与海相火山岩有关的块状硫化物矿床、岩浆铜镍硫化物型矿床、沉积变质型铁矿、浅变质含碳细碎屑岩型金矿和韧性剪切带型金矿床，近年来在斑岩型铜矿床的找矿工作有了新进展。

Veined,stockwork and alteration-sheathed gold ores have been found in the area,belonging to four genetic types:the volcanic hydrothermal ores related to early—middle Carboniferous volcanism; subvolcanic hydrothermal ores related to intermediate—acidic porphyry intrusions; hydrothermal ores to the granitic intrusion and dynamo- hydrothermal ores related to regional dynamic metamorphism along the faults.

矿石类型有含金石英大脉型、石英网脉型和蚀变岩型。矿床成因类型有4种：一为火山热液型，其成因与区内早—中石炭世火山作用有关；二为潜火山热液型，与中酸性斑岩体侵位有关；三为岩浆热液型，与花岗质岩浆的侵位有关；四为动力变质热液型，沿断裂带分布于蚀变玄武岩中，系区域动力变质作用的产物。

A systematic study on S and/or Pb isotopic compositions of the copper-bearing porphyries, ore minerals and andesite of the deposit shows that S isotopic compositions of ore minerals are similar to those of porphyries.

矿石矿物（208Pb/204Pb=37.917~38.230，平均值38.075；207Pb/204Pb=15.528~15.614，平均值15.571；206Pb/204Pb=17.929~18.082，平均值17.981）与矿化斑岩(208Pb/204Pb=37.832、37.883，207Pb/204Pb=15.529、15.538，206Pb/204Pb=17.906、17.910)以及安山岩(208Pb/204Pb=37.816~37.884，207Pb/204Pb=15.549~15.562，206Pb/204Pb=17.845~17.919)的初始铅组成基本一致，变化范围较小，表明三者具有相同的来源；在铅构造模式图上，所有样品铅同位素均位于造山带演化线上或附近，在铅同位素源区判别图中，均落入造山带和下地壳区域，这表明Pb主要来源于壳幔混合。

The fluid geochemistry research bears out the ratio of W/R becomes more few from epithermal to porphyry.
