摘　　要：Microstructure and mineralogical composition of six jade pieces excavated from Yujiawan,Gansu Province,China,were investigated by using scanning electron microscopy and energy-dispersive x-ray spectrometry (SEM-EDX),x-ray fluorescence spectrophotometer (XRF),x-ray diffractometer (XRD) and Infrared spectrometer (FT-R). One grey nephrite,three grey-white nephrites,one marble and one essonite were identified. As a result of comparative research on the elemental composition of alterative and unaltered jades,we propose that the alteration of nephrite was a process that calcium ions in burial soil diffused into the nephrite,then subsided and calcified ultimately.Microstructure and mineralogical composition of six jade pieces excavated from Yujiawan,Gansu Province,China,were investigated by using scanning electron microscopy and energy-dispersive x-ray spectrometry (SEM-EDX),x-ray fluorescence spectrophotometer (XRF),x-ray diffractometer (XRD) and Infrared spectrometer (FT-R).
