摘要
安溪长坑花岗岩体呈不规则状,与围岩接触界线呈港湾状。根据长坑岩体岩石学及岩石地球化学特征,探讨其与铁、钼矿等成矿关系。分析认为,该岩体侵入过程中带来热源和成矿物质为矽卡岩型铁矿、热液型钼矿成矿提供了内在条件。对长坑花岗岩体与船山组、棲霞组接触带寻找矽卡岩型铁矿,岩体内部云英岩带寻找热液型钼矿具有指导意义。
Anxi Changkeng granite is irregularly shaped, the boundary line of rock is embaymento This paper analyzes the granite＇s petrology and geochemistry in Changkeng, discussion about relationship of mineralization with iron and molybdenum minerals, etc. The research proves that in the process of granite＇s invading, it can bring heat source and metallogenic material what can provide internal conditions for the skarn type iron ore＇s mineralizing and hydrother- mal type deposit＇s mineralizing. The results obtained have instructive function for finding skarn type iron ore on the rock and late paleozoic group＇s contacts and Qixia group＇s contacts, and finding hydrothermal type deposit on the greisen zones inside rock.
