| 摘 要： | 该文从总结雪峰山中段金锑矿区构造控矿规律和成矿预测的角度，采用Ｘ射线衍射法开展了成矿期控矿构造带的韧－脆性变形岩石且构的研究。根据Ｘ射线岵组图特征分析探讨了岩石变形时的力学性质、主应力方位，并结合宏观地质特征对控矿构造进行了运动学和动力学分析，得出ＮＥ向构造带为压扭性导矿、控矿构造，运动方向为ＳＥ－ＮＷ，主压应力属ＮＷ－ＳＥ系统；ＮＷ向构造带为张扭性容矿构造，属ＮＥ向的伴生或派生构造。

| Abstract: | 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. |
