| 中文摘要: |
| 近年在山东胶莱盆地的北缘发现了一种新的金矿类型———层间滑动角砾岩型金矿。研究表明该类矿床赋存于中生代盆地盖层与变质基底接触带附近的低角度层间滑动断层中 ,该断层带具有延伸大、低角度、倾向滑动和层带结构等特征。主要工业矿体受层间滑动构造角砾岩带控制。低角度层间滑动断裂带为金矿成矿提供了十分有利的构造和物理化学条件 |
| 英文摘要: |
| In recent years, the new type gold deposit, Interlayer gliding breccia -type gold deposit, Such as Pengjiakuang, Dazhuangzi and Fayunkuang gold deposits had been discovered on the North margin of Jiaolai basin. The gold deposit occurs in a low- angle anormal fault between conglomerate of Early Cretaceous Laiyang Formation and metamorphic rocks of Lower Proterozoic Jingshan Group on the margin of Jiaolai basin. The interlayer gliding fault possesses the characteristics of deep- extension, low- angle, dip- slip, bed- zoned structure. The gold orebodies were controlled by main slip fault zone - structural breccia rock zone. The low- angle interlayer- gliding fault provided structure and physical- chemical conditions to ore- forming processes. |
