摘要
在对小秦岭变质核杂岩构造分析的基础上 ,笔者探讨了这种构造型式与金矿的构造关系 ,认为金矿分布与变质核杂岩构造具有对应性 ,提出本区金矿化具垂向构造分带性 ,即自上而下为构造蚀变岩型、石英脉型和蚀变糜棱岩型金矿 (河台式 ) ,并简要分析了这种构造控矿模式的找矿意义。
On the basis of analysis for the basic characteristics of Xiaoqinling metamorphic core complexe,the ralations of gold- ore to this tectonic style are discussed in the paper. Authers consider that the distribution of gold- ore is controlled by metamorphic core complexe and gold- mineralization has the vertical tectonic zonation.The types of gold- ore from upper one to lower are in the following:the tectonic altered- rocks,gold- bearing quartz veins and altered mylonites type.Besides,significance of prospecting of the vertical tectonic metalogenic zonation is stated too.
