为判断江阴高城墩遗址出土良渚文化玉器的地质成因和产地,利用外束质子激发X荧光技术(PIXE)、X射线衍射(XRD)、激光拉曼光谱(LRS)等无损分析技术对出土玉器进行了化学成分、矿物学特征分析。实验结果显示,46件玉器中67.4%的样品主要矿物组成为透闪石,玉料的质量较好,可能来自同一种成矿类型的矿床。研究表明无损伤分析技术是古代玉器研究的有效手段。研究结果为探索良渚文化遗址出土玉器的玉料来源提供了科学证据。
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.
