关于应力分析,从来都认为应该包括应力方向,应力大小以及其它有关因素的讨论。然而在构造应力场的地质研究中,七十年代以前却一直停留在应力方向的探讨上,无法深入地探讨古构造应力大小。七十年代末期以来,国外利用显微构造估算古构造应力值,取得了新进展,有了很大的突破。这个方法的基本原理是根据超显微构造中晶体的位错密室(Disloc-
With regard to stress analysis, it has always been considered that the discussion of stress direction, magnitude of stress, and other relevant factors should be included. However, in the geological study of tectonic stress field, the study of stress direction has been stuck in the seventies before, and the paleo-tectonic stress can not be discussed in depth. Since the late seventies, foreign countries have used microstructures to estimate paleo-tectonic stress values and made new progress with great breakthroughs. The basic principle of this method is based on the ultra-microstructure crystal dislocation chamber (Disloc-
