| 摘 要： | 根据小秦岭地区含金石英脉与糜棱岩的空间分布关系可将石英脉分为交代脉、拉张脉、剪切脉、角砾岩脉和裂隙脉等五种类型，它们是不同构造阶段的产物。脉体宏观构造、微观构造、包体测压数据及石英Ｘ射线研究表明，脉体的充填、定位与容矿空间扩张同时形成，容矿空间的形成是含金热液液压致裂作用的直接结果。本文详细研究了构造岩的岩石学、岩相学特征，并对构造岩的形成条件及与金矿化关系等做了初步探讨

| Abstract: | Tectonite are well developed in Xiaoqinling area and on the basis of correlations of spatal distribution between mylonite and auriferous quartz veins, they are divided into five types:metasomatic, extensional, shear, breccia and fisure veins. These veins were formed in different tectonic stages. Macrostructure, microstructure, inclusion pieszometer data and quartz X ray of the veins indicate that formation of the veins are contemporaneous with extension of host structures that were formed on fluid fracturing mechanism. |
