对一个花岗岩体变形的研究,表明了古应力场与由液态包体串所规定的微裂(即愈合微裂)几何学之间的关系.对液态包体串分布的统计研究得出下述结论:在许多标本上可观察到,包体串表现出颗粒尺度上的几个明显的优选方位;串的方向与花岗岩中的微裂及小尺度的裂异方向接近一致;串的主要方向平行于区域主压缩方向.因此,液态包体串是Ⅰ型裂纹,它可作为古应力场的极好标志.
A study of the deformation of a granite body shows the relationship between the paleot stress field and the geometry of the micro-cracks (ie, healed micro-cracks) defined by the liquid inclusions. The statistical study of the distribution of liquid inclusions leads to the following CONCLUSIONS: It has been observed on many specimens that the inclusion body string exhibits several distinct preferred orientations on the grain-scale; the direction of the string is approximately the same as the direction of the cleavage of the micro-fissures and small-scale granites; the main direction of the string is parallel Therefore, the liquid inclusions are type I cracks, which can be used as an excellent indicator of the paleo-stress field.
