三星堆及金沙玉器的产地溯源

Origin of Sanxingdui and Jinsha Jades

摘要:

利用拉曼光谱、电子探针和电感耦合等离子体质谱仪（LA?ICP?MS）对龙溪软玉的谱学特征以及化学成分进行测试，并与三星堆玉器和金沙玉器进行对比分析。结果表明，三星堆闪石质玉器的拉曼光谱与龙溪软玉均具有674 cm^-1的特征峰。主量元素投图说明，龙溪软玉的成矿与白云岩有关，而三星堆闪石质玉器中部分和白云岩相关，此外还有部分玉器的成矿和蛇纹岩有关。龙溪软玉的稀土元素特征和金沙遗址玉器具有较高的相似性，结合三地之间的距离、玉器外观等因素，推测四川龙溪是三星堆玉器和金沙玉器玉料的来源地之一。

Abstract:

In this paper， the spectroscopic characteristics of Longxi nephrite were analyzed by using Raman spectroscopy， electron probe， and inductively coupled plasma mass spectrometry （LA-ICP-MS） . In addition， the chemical composition was tested and analyzed， and compared with Sanxingdui jade and Jinsha jade. The results show that both the Raman spectra of Sanxingdui amphibole jade and Longxi nephrite have a characteristic peak of 674cm-1. The majorelement mapping shows that the mineralization of Longxi nephrite jade is related to dolomite， while part of the Sanxingdui amphibolejade is related to dolomite， and the mineralization of some jade artifacts is related to serpentine. The rare earth element characteristics of Longxi nephrite and the Jinsha Site have a high similarity. In combination with factors such as the distance between the three places and the appearance of the jade， it is speculated that Longxi， Sichuan is one of the sources of jade materials for Sanxingdui and Jinsha jade.
