Abstract

The space distributions of differential stress and principal stress in Fushan gold field are got from measuring tectonic differential stress value.Results show that the gold orebodies are always located in the areas where the tectonic stress value varies highly,not the minimum or maximum.Based on strain measurement and analysis of susceptibility anisotropy,the tectonic strain fields of the diagenetic and mineralization periods in Fushan gold field are given respectively.There was a transition of stress field from NW trending compression to NE trending compression during mineralization,and the tectonic environment of minerallization was changed from shear compress to shear -extension.
