矿山地质中的矿床变形特征及成矿控制研究

Study on deformation characteristics and metallogenic control of ore deposits in mine geology

针对矿床研究和深部资源勘查方法难以探测成矿斑岩体的问题,提出了矿山地质中的矿床变形特征及成矿控制研究。从宏观和微观变形角度分析矿床变形特征,根据矿山地质断裂上下盘相对运动方向,判断剪切指向和运动学特征。根据各个矿体特征,确定劈理、面理、片麻理构造控矿因素;分析成矿前和成矿期的褶皱,确定褶皱构造控矿因素。依据成矿控制因素,判断成矿斑岩和矿体,为矿山地质找矿提供依据。

In view of the problem that it is difficult to detect the ore-forming porphyry by the methods of deposit research and deep resource exploration,this paper puts forward the research on the deformation characteristics and metallogenic control of the deposit in mine geology.The deformation characteristics of the deposit are analyzed from the macro and micro deformation angles,and the shear direction and kinematic characteristics are judged according to the relative movement direction of the upper and lower walls of the geological faults.According to the characteristics of each ore body,the ore controlling factors of cleavage,foliation and gneissic structure are determined;the fold before and during mineralization is analyzed to determine the ore controlling factors of fold structure.According to the ore-forming controlling factors,the ore-forming porphyry and ore body can be judged,which provides the basis for mine geological prospecting.
