The mineralogical characteristics of garnets from Xinditaga Group, Kuruk Tag, Xinjiang, have been rarely discussed by former researchers. In this paper, the mineralogical features of the red garnets produced in this area were investigated by using hydrostatic methods, refractometer, spectroscope, electron microprobe analysis and X-ray powder diffraction analysis. With regard to garnets formed in different metamorphic stages, the results of EPMA show that from the garnet’s core to rim, the amount of almandine end-member tends to increase, namely the mole fractions of the almandine end-members of samples Garnet 1, Garnet 2, Garnet 3 and Garnet 4 are 63.906%～72.408%, 65.663%～71.880%, 64.689%～71.711% and 50.011%～71.780%, respectively.
