A STUDY OF ORE-CONTROLLING STRUCTURES ON GOLD AND ANTIMONG IN THE MID-XUEFENG MOUNTAIN, HUNAN PROVINCE

A study of the fabrics of ductile-brittle rock deformation during the mineralization epoch by X-ray diffraction method is made. The aim is to find out the structural control of the gold and antimony in the Mid-Xuefeng Mountain so as to predict its distribution and enrichment. The results show that the NE-trending compresso-shear structural belt may serve as the passage way for the SE-NW ore fluid flow under a stress regime with the greatest principal stress trending NW-SE, and the NW-SE trending tenso-shear structural belt associated with and derived from the NE-SW-striking structures as the host structure and described.
