随着近代岩石实验变形研究的深入开展,研究岩石组构的动力学方法逐步得到推广和应用,但从已经发表的大量文献资料来看,用这种方法来研究挽近地质时代以来,特别是第四纪以来的应力作用方式,并不多见。笔者在金川矿区工作时发现:在挽近构造变动所涉及的第四系砂砾岩中,显微构造形 With the deepening of the research on the experimental rock deformation in modern times, the dynamic method of studying the rock structure has been gradually popularized and applied. However, based on a large amount of published literatures, this method has been used to study the recent geological era, especially Since the Quaternary stress effects, and rare. When working in Jinchuan Mining Area, the author found that among the Quaternary glutenite rocks involved in structural transformation in the Qianjin, the microstructures
