Structural and nondestructive componential analysis on several Nephrite from different provenances.
几种不同产地软玉的岩相结构和无破损成分分析

Proton induced X-ray emission(PIXE),X-ray diffraction(XRD),scanning electron microscope(SEM)and laser raman spectrum(LRS)were used to analyze the mineralogy of several nephrite samples from Xinjiang(China),Russia,Canada and New Zealand.Specimens from different localities were compared based on their components and micro-morphology.The experimental results show that nephrite are tremolite structures which transmit to the actinolite with the increase of iron content.Due to its fibrous matted structure,Hetian jade hold the homogeneous and lustrous surfaces.The nondestructive experimental methods also provide the technical support for research on the Chinese valuable ancient jade.
