Characteristics and tectonic significance of trace elements in Chaganhada rock mass, Weijing area

The paper analyzed the tectonic evolution of the Weijing area and the trace rare earth elements in the Chaganhada rock mass. It is concluded that the granite samples of the Chaganhada rock mass are relatively rich with K, Rb, Th, U, Pb and Nd and relative depletion in Sr, Ba, Ti, Nb and Ta. The results show that the Σ REE is high, light and heavy rare earth fractionation is obvious, light rare earth enrichment and heavy rare earth loss; By constructing the environmental discriminant diagram, it shows that the rock mass was formed in the post collision period from compressional to extensional tectonic environment.
