| 摘 要： | 辽宁瓦房店地区的3个金伯利岩带内的典型金伯利岩管产于NE向、NNE向与近EW向3组构造薄弱带中,并严格受其控制;3组构造交汇部位是今后找寻金伯利岩管的有利部位。构造期次对该区50号岩管具有明显控制作用:早期近EW向挤压破碎带为金伯利岩管的导矿构造;中期NE向断裂为控矿构造;晚期NNE向断裂、NW向断裂,对金伯利岩体起破坏作用。50号岩管及其周边金伯利岩体与构造盆地具有较明确的关联性;野外调查表明,50号岩管周边也曾发生过由E向W方向(或由SE向NW方向)的水平运动,且三维建模显示现在50号岩管不是岩体的根部,应在其东部或东南部寻找可能的剩余部分。

| Abstract: | Typical kimberlite tube in three kimberlite belts in Wafangdian area Liaoning province occurs at and is controlled by the structurally weak zones of the NE fault, NNE fault and near EW fault. Cross points of the three faults are the favorable kimberlite tube prospecting targets. Fractured zone of the near EW fault is the kimberlite tube No.50-conduct structure, weak zone of the middle NE fault the control structure, the late NNE and NW faults the destructive. No.50 kimberlite tube and it''s surrounding kimberlite are clearly related to the tectonic basin. Field survey shows evidence of horizontal SE-NW movement in the kimberlite area. The 3D modeling shows that No.50 kimberlite tube has not root and the root should be in the east or southeast. |
