| 中文摘要: |
| 沙木坞矿区地处我国重要成矿带——钦杭成矿带的东段北缘,通过对该区开展地质找矿工作,共圈定了7条矿体。文章基于矿区地质概况和矿床地质特征描述,对矿床成因及找矿标志进行研究和分析,总结出该矿床形成于中生代燕山早期花岗岩与奥陶系砚瓦山组和胡乐组灰岩的接触带上,矿床严格受夕卡岩和断裂构造控制,呈脉状产出,矿床成因属于接触交代(夕卡岩)型。 |
| 英文摘要: |
| The Shamuwu iron polymetallic deposit occurs at the northern edge of Qinzhou-Hangzhou metallogenic belt, one of key belts in China. Based on seven orebodied were outlined by geological prospecting work in that area. On the basis of description of geological conditions and deposit geology characteristics, the deposit genesis and prospecting criteria were analyzed and studied.It is concluded that the deposit was formed in the contact zone between the late Mesozoic Yanshan granite intrusion and Ordovician limestone of Yanwashan and Huyue formation.The orebodies are strictly controlled by skarn and fracture structure in forms of vein type.The deposit belongs to contact metasomatic type deposit (skarn type). |
