新桥硫化物矿床构造特征及其控矿规律

The structure characters of Xinqiao sulphide deposit and its ore-controlling regularities

介绍了新桥多金属硫化物矿床成矿前、成矿期、成矿后各期构造特征。提出了该矿床受燕山晚期的NNE向、EW向及层间伸展滑脱构造复合控制 ,EW向构造为导岩构造 ,NNE向构造为导岩导矿构造 ,层间伸展滑脱面为储矿构造的观点。

The paper introduced the characters of Xinqiao sulphide deposit during the whole process of ore formation. It is put forward that the deposit are controlled by NNE、EW and interbeded slip structures in the later Yanshan period. The EW structures are magmatite forming, the NNE structures are magmatite forming and ore forming, and the slip sheet structures are controlled by the deposit′s shape.
