通过对拉拉矿床矿物共生组合、矿物生成顺序、矿石特征的研究,发现其矿石矿物以磁铁矿为主,铁和铜的硫化物次之,并含有大量稀土矿物和自然金。拉拉矿床至少经历了两期成矿作用:早期为区域变质成矿作用,晚期为热液成矿作用。早期形成Fe R...通过对拉拉矿床矿物共生组合、矿物生成顺序、矿石特征的研究,发现其矿石矿物以磁铁矿为主,铁和铜的硫化物次之,并含有大量稀土矿物和自然金。拉拉矿床至少经历了两期成矿作用:早期为区域变质成矿作用,晚期为热液成矿作用。早期形成Fe REE P矿化,晚期为Cu Mo Au Co (U)矿化。根据这些特征,首次指出该矿床属于铁氧化物 铜 金 铀 稀土型矿床,而不是以往所称的块状硫化物型铜矿。展开更多
