摘要:
通過總結福建省南靖縣南坑鉬礦床的地質特征,認為該鉬礦床為斑巖型鉬礦床,鉬礦體主要賦存于燕山早期花崗巖與文賓山組接觸帶,主要產在燕山早期花崗巖體內,受緩傾斜的石英脈和網脈狀石英細脈控制,礦石類型為石英粗脈型和石英細脈型。該鉬礦床具有弱磁異常,原生暈、次生暈異常發育, 鉬次生暈異常在深部見礦效果較好; 與鉬礦體關系密切的蝕變主要有云英巖化和硅化,找礦標志主要為燕山早期花崗巖、白樓—下樓斷裂帶、晚三疊世文賓山組、云英巖化、硅化及物化探異常,以上認識對區域尋找類似鉬礦床具有參考價值。
Abstract:
Through summarizing the geological characteristics of the Nankeng molybdenum deposit in Nanjing County, Fujian Province, this study concludes that the deposit belongs to porphyry-type molybdenum ore deposit. Molybdenum orebodies occur mainly along the contact zone between early Yanshanian granite and surrounding rock Wenbingshan Formation, predominantly within early Yanshanian granite. The orebodies are controlled by gently-dipping quartz veins and stockwork quartz veinlets. There are two types of ores: quartz vein and quartz veinlets. The Mo-bearing deposit is characterized by weak magnetic anomalies, well development of primary halo and secondary halo, with the secondary halo anomaly showing good mineralization especially at depth. Alteration closely related to Mo mineralization contains greisenization and silicification and etc. The indicators for prospecting mainly are early Yanshannian granite, Bailou-Xialou fault zone,Wenbingshan Formation of late Triassic, greisenization and silicification, geophysical and geochemical anomaly, etc. The understanding above is of some references for finding similar molybdenum ore deposits in the area.
