Abstract: 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.
