| 摘 要： | 白乃调金矿区的节理包括东西向剖面共轭剪切节理，北东－北西向平面共轭剪切节理，北北东向剖面共轭剪切节理。与之相应的断层有近东西向逆断层，北东向和北西向的平移断导以及北北东向的斜冲断层。此外，北东向断层的低序次构造亦呈北北东走向，但其性质为平移断层。东西向、北东和北西向断裂形成于南北向挤压构造应力场。它们控制了主要含金石英脉展布。其中，２６号主矿脉就位于北东向平移双断裂－白乃庙断裂的北北东向低序次平移

| Abstract: | There are EW direction conjugate shear joints in cross section, NE and NW direction conjugate shear joints in plane and NNE direction conjugate shear joints in cross section in Bainaimiao gold mine area,Inner Mongolia. There are also EW direction reversed fault, NE and NW direction strike-slip faults as well as NNE direction oblique reversed fault. In addition, the secondary generation faults of NE direction strike-slip fault also run in NNE direction, but they are strike-slip fault. Although all ore veins take their place in the faults formed by SN direction compression, they belong to pre-mineralization faults. During mineralization, partial tectonic stress field caused by magma intrusion made the faults open and controlled ore-bearing quartz veins. |
