| 中文摘要: |
| 红海VMS型矿床位于卡拉塔格古生界火山隆起区西南边缘的斜坡地带。矿体产于海相火山碎屑岩层中,受多组断裂构造控制,具有典型的上部块状铜锌矿体,下部网脉状铜矿体的二元结构特征,成矿元素具有明显的空间分带特征。从块状矿体到矿体上盘呈块含铜黄铁矿矿石→黄铜矿石→铜锌矿石的变化规律,矿物组合变化规律为:黄铁矿+黄铜矿→黄铜矿±黝铜矿→黄铜矿+闪锌矿±黝铜矿±方铅矿±黄铁矿。从块状矿体核部向边部,矿石中Cu的含量呈递减趋势,Zn的含量与Cu的含量成负相关关系；网脉状矿体Cu含量变化不大。块状矿体的Cu品位大于网脉状矿体。 |
| 英文摘要: |
| The Honghai VMS deposit is hosted on the slope at thesouthwest edge of the Paleozoicvolcanicuplift zonein the Kalatage, Xinjiang. The orebodies occur in the marine volcanoclastic rocks, which is controlled by many faults and has typical characteristics of dual-structure asthe upper is massive Cu-Zn ore-body and the bottom is vein Cu ore-body.The metallogenic elementS has obvious spatial distribution characteristics. From the massive ore-body to the upper wall of ore-body, the oresvarylike chalcopyrite-pyrite→ chalcopyrite→chalcopyrite-sphalerite, the mineral assemblagevary in the pattern like chalcopyrite+pyrite →chalcopyrite ± tetrahedrite →chalcopyrite+ sphalerite ± tetrahedrite ± galena ± pyrite. From the inner to outer of the massive ore-body, the grade of Cu decreases, the relationship between the grade of Cu and Znis negative,the variation of the grade of Cu in the vein ore is not obvious and the grade of Cu in the massive ore is higher than that it in the vein ore. |
