A large number of Xinlongwa and Hongshan jades have been unearthed or collected in Bairin Right Banner,Inner Mongolia Autonomous Region,but there have been few systematic material studies.In our study,portable instruments such as Raman and X-ray fluorescence(XRF)spectrometers were used to conduct non-destructive testing and analysis on 74 Xinglongwa and Hongshan jades from this area.After qualitative and quantitative analyses,most jades in this batch were identified as nephrite,while the others were identified as dickite,calcite,serpentine,mica and fluorite.The nephrite jades can be divided into three groups according to the peak counts of XRF spectra:those of Xinglongwa period are concentrated in Groups B(light green)and C(light yellow),and those of Hongshan period are concentrated in Groups A(dark green)and B(light green).The further studies were focused on the provenance information of those jades with the help of the geologic mineralogical method.It can be inferred that the nephrite articles as well as a few articles made of other materials were sourced from Xiuyan area of Liaoning Province,while most of other materials were obtained nearby.
