A review of research achievements on REE geochemistry of tungsten deposits in China

The composition and characteristic parameters of rare earth elements (REE) in tungsten deposits provide mineralization environment as well as fluid and source information. The achievements in the study of geochemistry of rare earth elements in tungsten deposits in China are very abundant, but it is still necessary to make a national systematic summary from the perspective of single mines. In this paper, statistics of more than 300 sets of rare earth elements of tungsten deposits in different types of deposits published from 1990 to 2016 were investigated. The results show that total REE values and distribution curves in different types of tungsten deposits are different due to different sources and ore-forming physicochemical conditions. The Eu from different types of tungsten deposits exhibits negative anomalies, which implies that the ore-forming environment was somewhat reducing. There are some interrelations between wolframite and its ore-bearing granite, However, but REE in wolframite did not enrich with magma-fluid differentiation.
