By use of proton induced x-ray emission (PIXE),x-ray diffraction (XRD) and laser Raman spectroscopy (LRS),the chemical composition and mineralogic characteristics of the jade artifacts unearthed from Gaochengdun site in Jiangyin city have been studied.The raw materials used for making these jade artefacts and their resources are discussed based on the experimental results.These analyses shows that the main minerals of these 46 jade artifacts is 67.4% tremolite,and that they have good quality and may have been taken from deposits of the same mineralization type.The present study indicates that the non-destructive analytical techniques offer an effective new means for characterizing ancient jade artefacts.These research results provide a scientific means for tracing the sources of raw materials used for jade artefacts of the Lingzhu Culture.
