本世纪六十年代以来,岩石冲击变质作用的研究很受重视,这项工作的开展是与地下核爆炸和空间计划紧密联系的。 地下核爆炸是在岩体中产生特征冲击效应的最好方法,其规模和矿物变形程度可以与陨石撞击相比。为了搞清岩石经受陨石撞击或核爆炸冲击所产生的永久变形的性质和程度,有一些学者进行了一系列人工冲击试验,进一步丰富了有关岩石冲击变质作用的知 Since the 1960s, the study of rock metamorphism has received great attention. This work is closely linked with the underground nuclear explosion and space planning. Underground nuclear explosions are the best method of generating characteristic shock effects in rock mass, and their size and degree of mineral deformation can be compared with meteorite impact. In order to find out the nature and extent of the permanent deformation of the rock subjected to meteorite impact or nuclear explosion impact, some scholars conducted a series of artificial impact tests to further enrich the knowledge of rock impact metamorphism
