摘要
安溪青洋石墨矿矿源层为该区二叠系童子岩组第三段煤层,受成矿期后断裂构造以及岩脉侵入的影响,属后期热液接触变质层控矿床。通过对该区成矿构造条件及热液变质作用的关系的研究分析,探讨了石墨矿床的成因以及控矿条件,为周边地区找矿提供了方向。
The source bed of graphite deposit in Qingyang, Anxi is coal seams in No.3 member of Tongziyan Formation, Permian System. Affected by post mineralization epoch faulted structures and intrusive dikes, the deposit belongs to a succeeding hydrothermal contact metamorphic strata-bound mineral deposit. Through relation between structural condition and hydrothermal metamorphism analysis, the paper discussed the genesis and ore-control factors of the deposit, point out ore prospecting orien tation.
