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.
