广东海南岛石碌铁矿是我国著名的富铁矿,开采历史悠久。解放后,先后对该矿床开展了大量地质研究工作。但长期以来,对矿床成因一直存在较多争论,主要观点有热液接触交代说、沉积变质热液改造说和火山沉积变质说等。在火山沉积变质说中,多数人认为矿质来源于远源火山。 近年来我们在多次野外观察基础上,综合运用偏、反光显微镜、扫描电镜、岩石矿物光 Shilu iron ore in Hainan Island, Guangdong Province is China’s famous iron ore rich in mining has a long history. After the liberation, has carried out a large number of geological research work on the deposit. However, for a long time, there have been many controversies about the genesis of the deposit. The main points of view are the hydrothermal contact, the alteration of sedimentary metamorphic hydrothermal fluids and the metamorphism of volcanic deposits. In volcanic sedimentary metamorphism said that most people think that the mineral comes from the Yuanyuan volcano. In recent years, we have observed many times on the basis of the field, using a combination of partial, reflective microscopy, scanning electron microscopy, rock mineral light
