中文摘要:
      甲乌拉—查干铅锌银矿床属于木哈尔成矿亚带,大地构造位置处于大兴安岭褶皱带与外贝加尔褶皱带的衔接地带,额尔古纳—呼伦深断裂(以下简称额—呼深断裂)以西,西伯利亚地台东南外缘。属中朝地台与西伯利亚地台之间的过渡型地壳构造区。矿床具备良好的成矿地质背景。在十二五期间,通过对已有地质资料综合分析研究,发现在甲乌拉—查干铅锌银矿床深部第二找矿空间(500~1500 m)还有很大找矿前景,是新增资源储量的重点区域。根据矿区地势平坦,确定勘查手段以地表钻探为主的探矿思路。按照“由已知到未知、由浅入深、由疏到密、由内到外”的原则,布置探矿工程,开展甲乌拉—查干铅锌银矿床深部和外围的地质探矿工作。在第二找矿空间取得了重大突破,新增333类以上矿石储量1118万t,铅金属量59万t,锌金属量60万t,铜金属量6000 t,银金属量1261 t。
英文摘要:
      The Jiawula- Chagan Pb-Zn-Ag ore deposit occur in the Muhal metallogenic sub-belt. In geotectonic it is located in the junction part of Daxinganling fold belt and Transbaikal fold belt in aspect of tectonic, western side of Eerguna - Hulunbeier deep fault zone, and southeastern part of Siberian platform, which belongs to the transitional crustal tectonic area between China platform and Siberia platform. There is favorable geological setting in the deposit area. Based on comprehensive analysis of existing geological data during the period of “Twelfth Five-Year Plan”, it is found there is a great prospecting potential in the depth of between 500 m and 1500 m in the Jiawula- Chagan Pb-Zn-Ag deposit, which probably increases the deposit resources. Considering the flat topography in the deposit area, the surface drilling programme was determined as main exploration approach. Finally a major exploration breakthrough was achieved in the Jiawula- Chagan Pb-Zn-Ag ore deposit area. The newly increased ore reserve is 11.18 million tons of ore (Class 333), containing 590 000 tons of lead metal, 600 000 tons of zinc metal, 6 000 tons of copper metal,and 1261 tons of silver metal.
