摘要
萑香洼金矿床产于华北陆块南缘中元古界熊耳群火山岩系中。根据区域地质背景和矿床地质特征分析了成矿地质条件,认为太华群为金的主要矿源层,燕山期岩浆活动为矿源层中金的活化、迁移、富集提供了动力和热液条件,区域性焦园断裂为主要导矿构造,F985含金蚀变构造带控制了矿体分布与产出。总结了找矿标志,指出了进一步找矿的方向。
Huanxiangwa gold deposit is formed in Proterozoic Xionger group volcanic rock in the southern range of North China landmass. Based on regional geological background and geological features of deposit, the paper analyzed the geological conditions of metallogeny, and holds that Taihua group is the principal zone containing gold, the activity of magmatism in Stage of Yanshan gave power and hydrotherm for the activation, migration and enrichment of gold, the regional Jiaoyuan fault is the main structure guiding the formation of gold, and F985 gold-contained tectonoalteration belt controls the distribution and output of orebody. Furthermore, the indicator is summarized, and proposed further ore-hunting orientation.
