七台河—牡丹江金成矿带,位于我国东北东部火山岩带及辽吉东部火山岩带北缘[1],亦属滨太平洋构造域成矿带组成部分。各时代尤其是中生代火山—次火山岩浆活动频繁,是金矿及多金属矿化集中区。本文通过收集大量前人资料,分析并归纳了七台河—牡丹江金成矿带的成矿物质来源、构造环境、金矿分布与构造控矿作用、金矿床类型及其地质特征,确立了未来在该地区寻找金矿方向,即在七台河—牡丹江金矿成矿带确定靶区,应综合考虑元古界麻山群、黑龙江群、黄松群地层分布的范围,浅成或超浅成中酸性侵入体及混合花岗岩出露的位置,深大断裂及次一级断裂的发育区,砂金矿床分布分布规律等地质成矿因素。
The Qitaihe-Mudanjiang gold metallogenic belt is located in the volcanic belt in the eastern part of Northeast China and the northern margin of the volcanic belt in eastern Liaodong [1], and is also part of the metallogenic belt in the foreshore Pacific tectonics. Various times, especially Mesozoic volcano - sub-volcanic magmatic activity is frequent, is the gold and polymetallic mineralization concentration area. By collecting a large amount of previous data, this paper analyzes and summarizes the metallogenic source, tectonic environment, gold distribution and tectonic control, gold deposit type and geological features in the Qitaihe-Mudanjiang gold metallogenic belt, and establishes the future In this area, the direction of the gold mine is sought. That is, the target area should be considered in the Qitaihe-Mudanjiang gold ore belt, and the distribution of the strata in the Proterozoic Tashan, Heilongjiang and Huangsong formations should be comprehensively considered. Body and mixed granite location, deep faults and secondary rupture of the development zone, distribution and distribution of placer gold and other geological mineralization factors.
