| 摘 要： | 对晴隆锑矿含矿层及围岩的稀土元素地球化学特征研究表明,其ΣREE变化较大,但REE配分模式较固定,以明显的负Ce异常、Eu正异常、分配曲线相对平缓为特征。对比该区玄武岩的稀土配分模式图后发现,两者差异较大。结合镜下岩(矿)石的结构和矿物组合特征以及野外实际资料,认为锑等矿质元素是盆地流体通过花鱼井、雷钵硐等NE向的深大断裂运移,由于氧化还原、温度和压力等物理化学条件的改变,沉积赋存于"大厂层"中。 |

| Abstract: | An investigation on the REE geochemistry of the ore-bearing strata and surrounding rock of Qinglong antimony deposit show that the ΣREE changes greatly while REE patterns is stable,characterized by the obviously negative Ce anomaly,positive Eu anomaly and flat REE distribution pattern.Comparison with the basalt＇s REE distribution patterns illustrate that there is significant difference between them.Microscopic characteristics of the surrounding rocks,ore structure and field observations indicate that the ore materials had been transferred through NE fault,such as Huayujing and Leibodong faults,and then deposited in ＂Dachang Layer＂ as a result of the change of the redox and P,T conditions. |
| Keywords: | Dachang Layer basin liquid REE antimony deposit of Qinglong Guizhou province |
