摘要
借助于两种变形产物的定向微观对比观测，鉴别高速变形微观特征标志。对比结果表明：石英冲击微页理、继形玻璃、切砾微断裂、撞击楔入、放射状破裂、碎砾随机排列和锯齿状破裂等变形形迹是典型高速变形微观标志。从而为天然古地震震源体的识别提供了客观依据。与此同时。
Microscopic characteristics of highspeed deformation are distinguished by means of directive microscopic comparative observation. It is shown that the deformation appearances are the typical microsymbols of highspeed deformation, such as quartz shock lamellae, thetomorphic glass, mineral twist and kink, gravelcutting microfractures, collision wedge, radial crack, gravel arrangement at random and sawteeth shape crack. An objective basis is provided for the identification of natural focus body of paleoearthquake. As a result, the authors early stage understanding is revised and perfected.
