| 摘 要： | 秋树湾铜钼矿床位于北秦岭造山带南侧靠近商丹断裂，铜矿赋存于北山角砾岩筒中，黄铜矿发育于角砾岩胶结物中。金属矿物简单，主要为黄铜矿、磁黄铁矿、闪锌矿和辉钼矿。矿石铅、硫同位素等表明成矿物质与深源浅成小斑岩体有关。氢氧同位素以及包裹体成分指示大气降水参与了成矿作用。铜钼矿形成于统一的接触交代成矿作用体系，后期热液使早期形成的矽卡岩发生退化蚀变并形成铜矿。

| Abstract: | Qiushunwan copper molybdenum ore deposit is located in south side of Northern Qinling orogenic belt and near to Shang Dan fault zone.The copper ore occured in the amphibolite in North mountain and chalcopyrite dereloped in the cement of the amphibolite mineral composition is simple,mainly including chalcopyrite, pyrohotite sphalerite and molybdenite.The ore lead isotope and S isotope data indicate that the ore forming metals are related to the deep source hypabyssal minor intrusion.The H isotope, O isotope and composition of fluid inchisions show that the meteoric water have joined to mineralization.The copper ore and the molybdenum ore are formed in an universal contact metasomatism ore forming system.As the regressive alteration take placed due to the action of later stage hydrothermal solution on the former stage skarn ,the copper ore are formed. |
