| 摘 要： | 海南石碌铁矿床是我国最大的富铁矿矿床,其矿床成因一直存在着争论,其中争议之一是矿床成因除与火山-沉积变质有关外,是否还与后期构造-岩浆事件的改造富集作用有关.前人曾对石碌铁矿床铁矿石、主要赋矿围岩石碌群以及矿区周围出露的花岗岩类进行过多方法同位素地质定年,但迄今尚未对矿区内分布的花岗斑岩类进行相应的工作.本文采用激光剥...

| Abstract: | The Shilu iron ore deposit,located in Hainan Province,is the biggest rich iron deposit in China. The genesis of the deposit is actively debated,some argue that besides the main stage mineralization of volcanic-sedimentary metamorphism,the late stage tectonic-magmatic events might have played very important role in reforming and enrichment of the ores. Many chronological studies on iron ores,Shilu Group(host rocks) and granitoid rocks around the mine have been done,but there are little chronological data abo... |
