| 摘 要： | 通过对主山冲金矿区的石英脉、蚀变矿石及区域上的远矿围岩和辉绿岩中稀土元素组成的比较,发现蚀变矿石与远矿围岩中的稀土模式基本一致,说明矿区成矿流体的稀土模式保持相对不变,故可用纯净石英脉中稀土的配分模式来代表成矿流体的稀土模式,从而利用稀土配分的示踪作用判断了矿区成矿流体来自深部.同时稀土元素也是热液型金矿成矿物质来源的良好指示剂,通过对石英、远矿围岩和辉绿岩中的稀土进一步比较表明,成矿物质属混合来源.

| Abstract: | REE compositions of quartz vein,altered rocks,wall rock of the area and diabase have been determined and compared.The result indicates that the REE patterns of altered rocks and wall rock are almost the same.This result also indicates that the REE patterns of ore-forming fluids in Zhushanchong gold deposit remains relatively unchanged.In this case,we can make the REE patterns of quartz vein as the REE patterns of ore-forming fluids.Consequently it is thought that the source of ore-forming fluid is from the ... |
