Late Permian granodiorites of Hanggale are characterized by relatively strong fractionation between LREE and HREE, enrichment of LREE, and without significant Eu anomalies, implying an I type granite. The depletion of Nb, Sr, P, Ti elements shows that such an arc granite has features of intrusive rocks related to subduction. In the R1—R2 diagram, most of the samples are concentrated along the boundary between the pre collision granite area and the post collision granite area. In the Nb—Y diagram, the samples fall into the area of the volcanic arc—syncollisional granite. In the Rb—(Y+Nb)diagram, the samples lie in the area of volcanic arc granite. In the Rb—Hf—Ta diagram, the samples all fall into the arc system. LA ICP MS zircon U Pb dating shows that granodiorite age is （ 257.9±3.1）Ma, the pluton age is （257.7±3.2）Ma, The Late Permian granodiorite of Hanggale was a pre collisional volcanic arc granite, and Hanggale area was a volcanic arc that belonged to active continental margin in Late Permian.
