The characteristics and the models of rare earth elements in the geological bodies and the hydrothermal water balanced with the adamellite were comprehensively studied in Aktishikan gold deposit, Nurt area of Altay, Xinjiang.And the behavior of rare earth elements during metasomatic alteration was discussed by using the isocon method of Grant. The results show that the rare earth elements are inert during metasomatic alteration, the hydrothermal water has no relation to the magmatic water, and the gold material sources mainly stem from the wall rock.
