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。
杏山北鉬礦床為膠東半島一典型矽卡巖型鉬礦床，位于著名牟平乳山金成礦帶和蓬萊棲霞金成礦帶之間，區域上位于膠東遼東鉬成礦帶，具有較好的成礦地質條件。通過對比膠東地區其他典型鉬礦床地質特徵，認為膠東半島鉬礦床存在兩期成礦時代；矽卡巖型礦床主要受近EW嚮斷裂構造控製，斑巖型礦床主要受近EW嚮與NE嚮斷裂複閤構造控製。通過物探異常預測，認為杏山北鉬礦床深部是尋找矽卡巖型和斑巖型銅鉬礦床的有利部位。

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 regional-ly.It has good geological conditions of ore forming.Through comparing geological characteristics with typical metallogenic conditions of Molybdenum deposits in other areas,it is indicated that there existed at least two ore forming 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.
