| 摘 要： | 孟恩陶勒盖大型银铅锌矿产于晚二叠世花岗岩杂岩体中心部位，矿床的主要容矿构造为一组沿东西向或近东西向展布向东收敛的脆性断裂带.成矿作用大致经历了4个阶段，形成了44条脉状矿体，按容矿构造分布划分为上、中、下3个矿脉群，其中主矿体9条，较大分支矿体9条，主矿体上下盘小矿体26条.矿床自下至上，具锌矿石-银铅锌矿石-银铅矿石的明显分带性.工业矿物主要为闪锌矿、方铅矿、深红银矿、黑硫银锡矿、自然银，主要有益组分为锌、铅、银，主要伴生有益组分有铟、镉、镓、铜、锡、金.矿床成因初步认为是裂隙充填脉状银铅锌多金属中温热液型，找矿标志明显.

| Abstract: | The large scaled Mengentaolegai Ag-Pb-Zn deposit in Inner Mongolia occurs in the center of the Late Permian granite complex. The host structure is a group of E-W-trending brittle fault zones. The metallogenesis experienced four stages, forming 44 ore veins in three levels, including 9 main orebodies, 9 large branch orebodies and 26 small orebodies. The deposit shows an obvious vertical zonation ofZn orebody, Ag-Pb-Zn orebody and Ag-Pb orebody from bottom to top. The commercial minerals are sphalerite, galena, pyrargyrite, eanfieldite and native silver. The useful elements are mainly Zn, Pb and Ag, with associated In, Cd, Go, Cu, Sn and Au. It is believed that the genesis of the deposit belongs to fissure-filled mesothermal Ag-Pb-Zn polymetal type, with evident prospecting indicators. |
