| 摘 要： | “三江”北西段是我国著名的“三江”有色及贵金属成矿带的一部分,以往工作程度极低,从而极大的影响了人们对整个区带成矿环境及成矿潜力的认识。近年来,随着地勘工作特别是大调查资源评价工作的不断发展与深入,区内各项地质资料已趋于完善,认识有了较大程度的提高。笔者根据野外实践,在区域成矿学、现代成矿理论等的指导下,结合地质、地球物理、地球化学和多元成矿信息分析,对三江北西段金属矿产资源成矿地质特征及找矿前景进行了总结。文章系统阐述了“三江”北西段的成矿地质背景,尝试划分了金属成矿系统及矿床类型,结合近年地质调查成果介绍了典型矿床特征及找矿新进展,在此基础上在成矿带内划分出3个成矿远景区,10个成矿预测区,并对其铜、铅、锌、银的找矿前景进行了评述。 |

| Abstract: | The northwestern segment of Sanjiang region (Three rivers) is part of the well-known Sanjiang nonferrous and precious metal mineralization belt. However, the backward geological work in the past had seriously affected our knowledge about the metallogenic setting and mineral potential in the segment. In recent years, as implementation of the assessment of mineral resources supported by China Bureau of Geological Survey, the situation has been largely changed. Combining with geology, geophysics, geochemistry and multi-factor analysis, this paper summarizes the metallogenic characteristics and ore prospecting potential in the northwestern segment of the Sanjiang metallogenic belt. Also, the paper discusses geological setting and classifies metallogenic systems and types through introducing typical ore deposits and new advances in prospecting. On the basis of all these, three ore-forming prospective areas and ten metallogenic prognosis areas have been determined, and prospecting potential of copper, lead-zinc and silver deposits have been evaluated as well. |
| Keywords: | the northwestern segment of Sanjiang region metallic ore deposits metallogenic characteristics prospecting potential |
