摘要
云开地区断裂构造对金矿的控制主要表现在两个方面：其一，断裂带带内的大断裂及大断裂的次级断裂，分别控制着区内的金矿带、矿带内的主要金矿床（点）及金矿体；其二，断裂构造的力学性质、活动期次及构造岩发育程度等，控制或影响着金矿的矿石组构特征、矿化期次及矿化强度等。本文还对断裂构造的控矿机制进行了探讨。
The fault controlled the forming of the gold deposits in Yunkai area，mainly shows asfollow：one is the fault zone，the macro—fault and the secondary fault contrelled the occur－rences of the gold mineralization，gold deposits（ore spots）and the ore—bodies respectivelyin the zone．The other is the mechanical property，stage and strength of the fault，they con－trolled or influenced the ore texture，the mineralization stage and the mineralization intensityect．In addition，the author study on ore—control mechanism of the fault．
