摘要
二道甸子金矿具有独特的成因机制及成矿控制条件。通过对该矿主矿带金矿化作用与古生代含碳变质岩系、弧形构造带以及与海西期黑云母花岗岩侵入作用之间的关系分析,指出后者是金矿成矿的主要控制条件;并据此总结出金矿富集规律和矿体预测准则,指出在矿区外国及深部存在进一步工作的找矿靶区。
Through investigating the relation between mineralization of main orebody and Paleozoic carbonaceous metan1orphic rocks. arctuate structure as well as theintrusion of Hercynian biotite granites,the authors propose a unique genetic mechanismand metalIogenesis-controlling factors for Erdaodianzi gold deposits.The study indicatesthat the granite intrtusion is the most imiportant metollogenesis-controlling factor.Therefore,this character is used to build up the gold enrichment regularity and ore bodyprediction criterion. The prospective target possibly xists in the outerskirt or in depth.
