| Abstract: | The REE patterns of primitive ore solutions in the Ailaoshan gold belt are characterized by significant enrichment of LREE,
a weak negative anomaly of Eu and a rather strong negative anomaly of Ce. In conjunction with the tension crust in the region,
the ore solutions are thought to be originated from a CQ2-rich fluid as a result of mantle degassing.
