摘要
大兴安岭地区是古生代古亚洲成矿域与中生代滨太平洋成矿域相互叠置的重要成矿区带,具有潜在的找矿前景.本文根据该地区的这一特殊的成矿地质环境,对矿床(点)分布、矿床类型、物化探异常特征及成矿地质背景进行了详细研究,总结了各成矿区带的成矿地质特征、成矿作用及成矿规律,进行了找矿前景分析,提出了以找大矿、富矿和找隐伏矿、半隐伏矿为主的找矿思路,并指出了本区找矿重点和找矿方向,提出了矿产工作的部署建议.
Daxinganling region, where the Mesozoic marginal-Pacific metallogenic domain superimposed the Paleozoic Paleo-Asian metallogenic domain, is a significant metallogenic province with prospecting potential. Based on such a specific metallogenic geological background, this paper studies the distribution and types of ore deposits, geophysical and geochemical anomalies and geological conditions for mineralization. The geological characteristics and mineralizing regulation of each metallogenic belt in the region are summed up. With analysis on the metallogenic potential, the prospecting directions for large and rich berried and partly-berried ores in Daxinganling region are pointed out.
