摘要
胜利达坂韧性剪切带是胜利达坂金矿区主要的控矿和容矿构造，控制着区内矿床、矿体及矿化体的分布。矿体、矿化体主要产于剪切带内的Ｄ、Ｐ、Ｒ型剪切裂隙中。成矿与剪切带的演化密切相关。成矿的有利部位是剪切带的边缘及次级剪切带问的过渡地带，它们是剪切带内应力梯度变化大的地带。
Shenglidaban dtlctile shear zone is the main ore-controlling and ore-hosting structure in Shenglidaban gold field. It controls the distribution of ore deposits, orebodies and mineralization bodies. Ore bodies and mineralization bodies mainly occur along the D, P, R type shearing cracks in the shear zone. Mineralization is closely related with the evolution of the shear zone. The shear zone boder and the belt of the transition between the secondary shear zones where the stress gradient changed greatly are favourable for ore-forming.
