| 摘 要： | 杏山北钼矿床为胶东半岛一典型矽卡岩型钼矿床,位于著名牟平-乳山金成矿带和蓬莱-栖霞金成矿带之间,区域上位于胶东-辽东钼成矿带,具有较好的成矿地质条件。通过对比胶东地区其他典型钼矿床地质特征,认为胶东半岛钼矿床存在两期成矿时代;矽卡岩型矿床主要受近EW向断裂构造控制,斑岩型矿床主要受近EW向与NE向断裂复合构造控制。通过物探异常预测,认为杏山北钼矿床深部是寻找矽卡岩型和斑岩型铜钼矿床的有利部位。

| Abstract: | Xingshanbei molybdenum deposit is a typical skarn type molybdenum deposit located in Jiaodong Peninsula in Shandong province. It located between the famous Mouping Rushan gold metallogenic belt and Penglai Qixia gold metallogenic belt, and located in Jiaodong Liaodong mineralization belt regionally. It has good geological conditions of oreforming. Through comparing geological characteristics with typical metallogenic conditions of Molybdenum deposits in other areas, it is indicated that there existed at least two oreforming periods in Jiaodong; skarn ore deposits are controled by nearly EW faults mainly, while porphyry deposits are controlled by nearly EW and NE faults. According to geophysical anomaly, it is regarded that the deep part of Xingshanbei molybdenum deposit is favorable for prospecting skarn type and porphyry type molybdenum deposits. |
