摘要
白乃庙金矿区共发育3组共轭剪切节理,即东西向剖面共轭剪切节理,北东向和北西向平面共轭剪切节理,北北东向剖面共轭剪切节理.此外还发育张节理和局部节理.通过节理组合分析以及节理与主应力关系分析,确定出节理的成因、形成顺序以及节理与控矿断裂之间的成生联系.
The Bainaimiao gold deposit in Inner Mongolia occurs in the Cu-bearing greenstone series of Bainaimiao group. Three sets of shear joints with different directions are developed in the rock, i. e. the E-W-trending sectional conjugate shear joints, NE- and NW-trending conjugate shear joints, and NNE-trending sectional conjugate shear joints. There are also some tensional joints and partial joints. The origin and forming order of joints, as well as the relation between joints and the ore-controlling faults are recognized with the analysis on joint sets and the relation between joints and principal stresses.
