大兴安岭中段,主要位于内蒙古兴安盟境内。多年来,国家地质科研机构始终将这一地区视为大兴安岭地区成矿与找矿的重点地段。在大兴安岭中段,燕山时期大规模的岩浆侵入活动除了岩浆演化、形成各种岩浆岩系列外,同时也为该域带来了极其丰富而宝贵金属矿产,燕山期是该域重要金属成矿时期。探讨燕山期成矿与岩体间相互关系(即成矿专属性)、成矿岩体主要矿物学标标型等特征,无疑具有重要意义。
Daxinganling middle section, mainly located in Inner Mongolia Xingan League territory. Over the years, the National Geological Research Institute has always regarded this area as the key area for mineralization and prospecting in the Greater Hinggan Mountains. In the middle section of Daxinganling, the large-scale magmatic intrusions during the Yanshanian period not only evolved magmatic rocks and formed various magmatic rocks, but also brought extremely rich and precious metal minerals to the region. The Yanshanian period is an important metallogenic period in this area. It is undoubtedly of great significance to explore the relationship between the Yanshanian mineralization and the rock mass (ie, the mineralization specificity) and the main mineralogical characteristics of the ore-forming rock mass.
