福建福安赤路—周宁咸格地区钼铜多金属矿地质特征及找矿远景分析

Analysis on Geological Characteristics and Prospecting Potential of Molybdenum-copper Polymetallical Deposit of the Chilu Fuan-Xiange Zhouning Area in Fujian Province

福安赤路—周宁咸格地区位于宁德寿山火山盆地东北边缘,区内金属矿产丰富,已发现有钼、钨、铁、铜、铅锌矿等矿床(点),通过总结分析这些矿床(点)的地质特征,认为区内存在斑岩型、矽卡岩型、岩浆热液型、火山-次火山热液型4种成因类型矿床,不同成因类型矿床的控矿因素不同。综合区内的成矿地质背景、地球化学特征、矿床(点)地质特征,认为该区具有较好的找矿潜力并提出具体找矿方向建议。

The area of chilu Fuan-xiange Zhouning is located in the northeast edge of the Shoushan volcanic basin in Ningde.The area is rich in metallic minerals.Molybdenum、tungsten、iron、copper and lead zinc deposits(spots)have been found.In this paper,the geological characteristics of these deposits(spots)are analyzed.It is considered that there are four genetic types such as porphyry type、skarn type、magmtic hydrothermal type、volcanic-subvolcannic hydrothermal type.The ore controlling facters of different genetic types are different.The metallogenic geological background,geochemical characteristics and geological characteristics of the deposits(spots)in the comprehensive area,it is considered that this area has better prospeting potential and proposes specific prospecting direction.
