哈达特陶勒盖银铅锌矿是兴蒙造山带近期取得较大勘查进展的中型银铅锌矿床，矿体主要赋存于4条NW向矿带中，控制矿体40个。矿体形态以脉状和透镜状为主，产状较陡。矿石矿物主要有闪锌矿、方铅矿和黄铜矿，未见单独银矿物，银主要分布在方铅矿中。矿物包裹体成分主要有黄铜矿、方铅矿、黄铁矿、石英和金红石等。根据野外观察和岩相学研究，将矿床成矿期次划分为3个阶段：石英-黄铁矿阶段、石英-多金属硫化物阶段和石英-碳酸盐-萤石阶段，这对进一步揭示矿床成因和扩大外围找矿具有重要意义。
哈達特陶勒蓋銀鉛鋅礦是興矇造山帶近期取得較大勘查進展的中型銀鉛鋅礦床，礦體主要賦存于4條NW嚮礦帶中，控製礦體40箇。礦體形態以脈狀和透鏡狀為主，產狀較陡。礦石礦物主要有閃鋅礦、方鉛礦和黃銅礦，未見單獨銀礦物，銀主要分佈在方鉛礦中。礦物包裹體成分主要有黃銅礦、方鉛礦、黃鐵礦、石英和金紅石等。根據野外觀察和巖相學研究，將礦床成礦期次劃分為3箇階段：石英-黃鐵礦階段、石英-多金屬硫化物階段和石英-碳痠鹽-螢石階段，這對進一步揭示礦床成因和擴大外圍找礦具有重要意義。

Hardat Tolgoi Ag-Pb-Zn deposit which located in Xing-Meng orogenic belt is a medium-sized deposit with larger exploration progress in the area.Ore bodies occurred mainly in 4 NW-trend ore belts who controlled 40 ore bodies.Additionally,orebody form was primary with vein and lenticular,and occurrence was steeper.Mineral inclusion composition mainly presented with chalcopyrite,galena,pyrite,quartz and rutile,etc.Meanwhile, deposit metallogenic period can be divided into three stages according to field observations and the study of petrography,namely,stage of quartz-pyrite,mineralization stage of quartz-polymetallic sulfide, quartz-carbonate-fluorite stage.The research results were of great significance for further revealing the genesis of mineral deposit and expanding the periphery prospecting.
