摘要
在深入研究大兴安岭中段地质构造、各种航空物探异常特征的基础上,对航磁资料进行了剖析,解释了磁场与多金属成矿密切相关的线—环构造及其火山岩基底情况等,总结出多金属矿藏的磁异常特征及其与线环构造、岩体、地层之间的关系,旨在为该区进一步部署多金属矿产勘查提供参考。
Based on the geological structure and the aero-geophysical features of the Da Hinggan Mountains,the authors interpreted the aeromagnetic data and,on such a basis,discovered the linear-circular structure and the volcanic rock basement.The relationships between the linear-circular structure,intrusive rock,Permian strata and gravity-magnetic features of polymetallic ore deposits were summarized.The work aims at providing references for polymetallic mineral exploration in this area.
