本文据锡矿山区古构造特征,运用相应的岩石破裂理论,对该区成矿期构造应力场进行数学力学的计算,其结果与该区古构造特征吻合得较好,并与国内外其它方法估算的古应力值可以对比。

Based on the certain structural style developed in Xikuangshan Area, Hunan Province, the stress values of mineralization are preliminarily estimated by mathematic mechanics in this paper. It reveals that the estimation of the stress values can be correlated to that of Paleo-stress values by other structure geologists using other methods. Therefore, it would be helpful for the discussions both on the various structures and the distributive mechanism of the ore deposits developed during mineralization in Xikuang shan Area.
