| 中文摘要: |
| 通过野外调查、样品采集、镜下鉴定和电子探针分析，发现地虎铜多金属矿床矿石矿物组成比较复杂，金属硫化物主要有黄铁矿(Py)、黄铜矿(Cp)、闪锌矿(Sp)、方铅矿(Gn)、黝铜矿(Te)、辉铜矿(Cc)和斑铜矿(Bn)，主要为一套中-低温热液成因的矿物组合，这些矿物多数呈半自形、星状、交代溶蚀等结构，具浸染状、块状构造。有用组分为Cu、Pb、Zn，主要以独立矿物的形式存在；经电子探针分析，发现部分Cu、Pb、Zn以细小颗粒矿物存在，此外，Zn还以类质同像的形式赋存在黝铜矿(Te)中。 |
| 英文摘要: |
| It is found that the mineral composition is quite complex by field investigation, the sample collection, the microscopic identification and the electron probe. The Dihu copper polymetallic ore deposit main metal minerals are pyrite, chalcopyrite, sphalerite, galena, tetrahedrite, chalcocite and bornite, it is mainly a set of mineral assemblages of medium - low temperature hydrothermal origin. Most of these minerals are semidiomorphic, stellate and metasomorphic structures with disseminated and massive structures. The main useful compositions are Cu, Pb and Zn, their occurrence status are mainly independent minerals. Some Cu, Pb and Zn are found in the form of fine mineral particles by the electron probe. In addition, the Zn has isomorphism. |
