砾石构造形迹是指发生在各种砾岩中砾石上的擦痕、压坑、裂隙、弯曲……等一系列构造现象。研究砾石构造形迹是一个与野外地质、同时又与岩石力学有关的重要问题。就已掌握的资料看,近年来国外有人对砾石上的裂隙类型和成因提出了较新见解;国内, 多限于报导第四纪冰川沉积物中的砾石构造形迹,并认为这些构造形迹是产生在搬运过程,或者是在冰层重压下产生的。关于下第三系砾石构造形迹的论述尚未见于文献。
Gravel structural footprint refers to a series of tectonic phenomena that occur on gravels in various conglomerates, such as scratches, crater cracks, cracks and the like. Studying gravel structural features is an important issue related to geology in the field and to rock mechanics. According to the information available, in recent years, some people in other countries have put forward new ideas on the types and causes of fractures in gravel. In China, they mostly confine themselves to reports of gravel structural features in Quaternary glacial sediments and believe that these structural features are generated in Carrying process, or generated under the pressure of the ice layer. The discussion about the tectonic trace of the Lower Tertiary gravel has not been found in the literature yet.
