| 中文摘要: |
| 通过对蒙古西北部金多金属矿床成矿地质背景、成矿区(带)特征、矿床类型、地质特征及矿床成因等进行综合分析,总结归纳了该区金多金属矿床成矿规律。通过分析典型金、银、铜铅锌、钨钼矿床的地质特征及控矿因素,结合区域综合找矿成果信息,认为蒙古西北部阿尔泰—萨彦成矿区成矿地质条件优越,斑岩型、夕卡岩型、韧性剪切带型和石英脉型金矿床,火山喷流沉积型、斑岩型铜铅锌矿床和与基性—超基性岩有关的铜镍矿床具有很大的找矿潜力。 |

| By means of comprehensive analysis on metallogenic background, features of metallogenic zones ,mineral deposit types and geological characteristics, and deposit genesis of the gold-polymetallic deposit in the northwestern Mongolia area, the paper summarizes the ore-forming regularities of the gold-polymetalic deposit in this region. Through the analysis of geological characteristics and ore-controlling factors of the typical mineral deposits such as gold, silver, copper-lead-zinc, tungsten-molybendium deposits with the combinations of integrated information of regional exploration achievements, the authors point out that there is favorable geological conditions for exploring porphyry, skarn, ductile-shear types of gold deposits, VMS sulphides type and porphyry type copper-lead-zinc deposits, and copper-nickel deposits associated with the mafic and ultra-mafic rocks along Altai-Sajan metallographic zone in the northwestern Mongolia area. |
