Abstract: Based on analysis of the REE′s geochemistry characteristics of different geological bodies in Bumo gold deposit，it is found that ∑REE decrease gradually form granitic vein，cataclastic rock，schist，gold ore bodies to quartzitic veins，and the REE distribution pattern of them is similar except quartzitic veins.It shows that granitic vein，cataclastic rock，schist and gold ore bodies has a certain inherited evolution characteristics and a closely mineralization relationships each other during the long geological process.However the REE distribution pattern curve of quartzite veins in lower crustal source is different from others，which provides a heat source for the mineralization.The mesoproterozoic Baoban group in the latter part of the metamorphic process causes the activation，migration of elements，providing the source material for the formation of gold deposits，and the Baoban group becomes source layer of gold deposit ore.The late granite veins are formed by partially melting the Baoban Group rocks in the deep crust.
