The experimental results of the analysis of the jade unearthed from the Fuquan hill by proton induced X -- ray emission (PIXE) are reported. By using PIXE technology
an appraisal of the jades unearthed from Fuquan hill can be made. The experimental results show that the Fuquan hill’s jades can be distinguished into two classes: Xiu jade and soft jade
and they are different to Xiaomeiling s jade but similar to the soft jade from Hetian
Xinjiang province. Furthermore
by analyzing proportion of iron and magnesium
some information of mineral structure and the color exuding of the jade from Fuquan hill can be obtained without any interference from impurity element.
