| 摘 要： | 大井矿床是我国北方重要的锡，铜，银，铅，锌等多矿种大型矿床，矿床铜，锡矿化即有关，又有分离，伴生的金矿化局部较好，可能与铜矿化阶段的黄铁矿化有关，浮选铜矿尾砂中的Au含量较高，有潜在的经济价值，独立的黄铁矿（毒砂）脉中的金，银矿资源应予评价，大井矿床东北约10km处叶腊石（巴林石）矿床中金矿化的发现为高S型浅成低温热液银-金-多金属矿床找矿提供了重要线索，说明大井外围有着较好的银-金-多金属矿找矿前景，大井矿床是次火山热液型锡-铜-多金属矿床，成矿物质可能来自基底及燕山期岩浆岩。 |

| Abstract: | The Dajing tin-polymetallic deposit is an important deposit in the north of China, which includes Sn,Cu,Ag,Pb,Zn and other metals. Sn and Cu are mostly related, sometimes separated. The associated gold mineralization is locally well-developed and may be related to pyritization during the stage of Cu mineralization. Gold is high in flotation tailing of copper and have potential economic value. Gold and sliver in independent pyrite(arsenopyrite) vein should be evaluated. The discover of gold mineralization in the Balinshi bloodstone deposit which is 10 km apart from the Dajing deposit is an important clue for the exploration of high sulfate-type epithermal Ag-Au-polymetallic deposit. There is a bright prospect for Ag-Au-polymetallic deposit in this area. Dajing deposit is a sub-volcanic hydrothermal one. The metallogenic metals possibly came from the basement or Yanshanian magmatic rock. |
