| 摘 要： | 新疆阿合栏杆银铅矿床位于新疆维吾尔自治区和田县郎如乡,地处昆仑山脉东端,受喜玛拉雅板块活动影响,构造复杂,岩浆活动强烈,岩石普遍变质,属中-低温热液型脉状银铅矿床。矿体受构造控制,呈脉状、透镜状产出于断裂破碎带之中,断层总体走向NE,倾向NW,倾角50°~70°。区内圈出3个矿带,分别为Ⅰ,Ⅱ,Ⅲ。矿体厚度和品位沿走向和倾向变化不大,赋存标高+5110 m^+4870 m。矿石为富铅银贫锌的铅银矿石,矿体围岩为黑云母二长花岗岩。通过地质勘查工作,系统地控制了区内的浅部矿体,新增银铅矿矿石资源量146.6万t。该文通过对矿床浅部矿体的形态、规模、矿石质量、矿石类型、围岩、矿床成因及成矿规律的分析研究,发现矿体形态结构简单,矿化均匀连续,严格受岩浆、构造控制,通过地表探槽平硐揭露及深部个别钻孔验证,矿体有向深部延伸的趋势,表明该区深部和外围仍具有良好的资源前景,对今后的找矿具有重要的指导意义。

| Abstract: | the Ahelangan AgPb deposit in Xinjiang is located in Langruxiang, Hetian County, Xinjiang Uygur Autonomous Region. It is located in the eastern end of the Kunlun Mountains. Affected by the activity of the QinghaiTibet Plate, the structure is complex, the magmatic activity is intense, and the rocks are generally metamorphosed. It belongs to the middlelow temperature hydrothermal vein AgPb deposit. The orebody is controlled by structure and occurs in veinlike and lenticular shape in the fracture zone. The fault generally strikes NE and inclines to NW with dip angle of 5070 degrees. Three ore belts are delineated in this area, namely, I, II and III. The surrounding rock of the orebody is biotite monzonitic granite. The ore is rich in lead, silver,and poor in zinc. The grade and thickness of the ore vary little along the strike and tendency, and the elevation is +5110 m to +4870 m. Through geological prospecting, the shallow ore bodies in the area were systematically controlled, and 1.466 million tons of silver and lead resources were added. Based on the analysis and study of the shape, scale, ore quality, ore type, wall rock, genesis and metallogenic regularity of the shallow ore body of the deposit, it is found that the shape of the ore body is simple, the mineralization is uniform and continuous, strictly controlled by magma and structure.Through trench and adit exposure, individual deep hole verification.The trend of deep extension indicates that there is still a good resource prospect in the deep and periphery of this area, which has important guiding significance for future prospecting. |
