REE Geochemistry of Zhushanchong Gold Deposit in Southeast of Guizhou

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 deep part.On the other hand the REE is also the tracer element of the ore-forming substance.We can find that the source of ore-forming substance is mixed-source.
