摘　　要：雪峰山中段为区域性剪切变形带，区内分布了众多与剪切带有关的金矿床（点）。作者分析了区域地质背景和剪切带特征，认为剪切带的规模、产状及形态，受控于发生剪切带变形的相对构造软弱层；剪切作用机制取决于水平挤压与剪切带的交切关系。The middle Xuefeng mountain is a regional shear deformation zone, there are many Au deposits which connect with the shear zone in the district. After the regional geological background and shear zone characteristics are analysed, author considers the scale, attitude and form of the shear zone are controlled by the relative structure softstrata which formed shear deformation, the shear mechanism depends on the intersection relationship between the horizontal compression and the shear zone.
