旋卷构造首先是李四光教授等发現并加以論述的,多属于軸近水平的一組箒状节理的綜合,因其展布范围非一般节理的概念所能概括,故被称作旋卷构造,它們是属于一种小型旋卷构造的范畴。这种构造和其他类型旋卷构造的出現,表明了地壳中岩块曾发生过旋扭运动,但由于岩体四周布滿岩石,所以岩体的旋扭程度往往是比較輕微,常生 The structure of the spiral coil is first discovered and discussed by Professor Li Siguang et al., And the synthesis of a group of zig-zag joints mostly near the axis of the shaft can be summarized as the concept of non-ordinary joints, so it is called the spiral coil structure , They belong to the category of a small spiral structure. The emergence of this structure and other types of spiral structures indicates that the crust has been subjected to rotational and torsional movements. However, due to the rock mass surrounding the rock mass, the degree of twisting of the rock mass tends to be relatively minor,
