福泉山良渚文化玉器的PIXE分析

摘要

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.%报道用质子激发X荧光技术(PIXE)分析福泉山良渚文化玉器的实验结果。采用PIXE方法可以可靠地鉴别福泉山玉器的种类，福泉山玉器中有软玉，也有岫玉。它们与江苏溧阳小梅岭玉在元素含量上差别很大，但软玉与新疆和田出产的软玉很类似。分析福泉山软玉铁镁占位比S，可排除杂质元素干扰，得到矿物结构和沁色信息。
