| 中文摘要: |
| 碱场铅锌多金属矿床位于得耳布干成矿带北段。赋存于新元古界额尔古纳河组大理岩、板岩地层中。矿化受 NNE 向断裂和构造裂隙控制明显,矿体呈脉状产出；矿区内发现4条铅锌矿体,I号、II号、III号、IV号,矿石中金属矿物以闪锌矿、方铅矿、黄铁矿为主；矿体及围岩发育中低温热液蚀变。该铅锌矿床属于中低温热液脉型铅锌矿床。 |
| 英文摘要: |
| Jianchang Pb-Zn deposit is located in the north of Deerbugan metallogenic belt. Orebodies occured in the marble and slate rocks of Ergunhe formation, the upper Proterozoic, controlled obviously by the NNE-trending fault and structural fracture. There are four Pb-Zn orebodies:I,II,III,IV. Metal minerals in ores mainly include sphalerite galenite and pyrite, developed medium-and-low temperature hydro-therm alterations. So we can draw an conclusion that Jianchang deposit is a typical medium-and-low temperature hydro-therm vein deposit. |
