封面故事：硅灰石矿石中的稠密浸染状斑铜矿。

Cover Story : Dense disseminated bornite in wollastonite skarn ore.

中期成矿矿石矿物主要是斑铜矿。

The late ores are mainly in massive big veins .

层状主矿体中金主要以细小的自然金形式包裹于斑铜矿和黝铜矿中。

Gold in stratiform major orebody is mainly included in bornite and tetrahedrite as fine grain of native gold .

凹地苴铜矿矿物在剖面上具从辉铜矿-斑铜矿-黄铜矿-黄铁矿分带现象。

Metal minerals in Wadizhou copper deposit appear to be zoning of chalcosine bornite chalcopyrite pyrite on the vertical direction .

氧化铜矿物主要为孔雀石，其次是硅孔雀石，少量蓝铜矿；硫化铜矿物主要是斑铜矿，其次是辉铜矿和铜蓝，少量黄铜矿。

Oxide copper minerals are mainly malachite , the second is chrysocolla , followed by a small amount of azurite ; and sulfide copper minerals are mainly bornite , followed by chalcocite and covellite , and a small amount of chalcopyrite .

主矿层中的矿化沿岩层厚度具有明显的垂直分带性，从底部到顶板为：辉铜矿→斑铜矿→黄铜矿→黄铁矿，为典型的化学沉积成因铜的硫化物排列组合特征。

Along thickness of strata , mineralization of master ore bed has obviously vertical zonality in the upward order of chalcocite → bornite → chalcopyrite → pyrite , It is indicated that typical arrangement assemblage feature of sulphide of sediment orogenic copper ore.

矿石主要原生金属矿物为辉铜矿和斑铜矿，次生金属矿物主要为孔雀石等。矿石结构构造比较简单，主要为结晶粒状及溶蚀结构和侵染状胶结构造。

The major primary metal minerals of ore are chalcocite and bornite , and the secondary metal minerals are malachite and azurite , etc. Ore texture and structure are simply , the ores are mainly in granular crystalline and dissolution textures and infection cementation structures .

研究认为，本区玄武岩具大陆拉斑玄武岩特征，铜矿属火山同生热液成矿叠加埋藏变质作用改造形成的玄武岩铜矿。

It is believed that the basalt in the area is characterized by continental tholeiite and the copper deposit belongs to a basalt type copper deposit formed by syn-volcanic hydrothermal mineralization superimposed by buried metamorphic transformation .
