Micro-deformation of quartz under dynamic action and its applications

Under the action of large stress, rocks and minerals undergo a series of deformation. By studying the microdeformation of specimens in controlled impact experiments, one can determine the relationship between microdeformation and pressure and thereby estimate the shock wave pressure endured by rocks in a underground nuclear explosion and use the data as a basis for classifying the damage zones in a free field explosion medium. The plane wave shock method is a good technique for simulating underground nuclear explosion. The plane shock wave experiment in granite medium at China's underground nuclear test site was discussed. Also describe the observation of microdeformation of quartz under petrographic microscopes and preliminary applications of distinguishing the rock damage zones in the free field after a underground nuclear explosion.
