中文摘要：为探索河南省贾湖遗址中绿松石的产地问题 ,通过对伴生岩石的岩相、物相分析以及对绿松石矿物的化学组成分析 ,对比研究了贾湖遗址与湖北、陕西、安徽等现代主要绿松石矿区的绿松石。结果表明 ,贾湖遗址的绿松石与上述现代绿松石矿存在较大差异。建议今后应重点研究河南省淅川县所产的绿松石。

英文摘要：The chief aim of the present work is to identify the provenance of the turquoise in Jiahu site(50007000 B.C.), which is located in Henan province of China. Because those turquoise samples were processed long ages ago, some of them were not carved and just simply polished and still adhere to the surrounding rock which is very helpful for people to know about the geological environment. According to the geological theory, turquoise formed in different places certainly have differences in many aspects. So the modern samples of main turquoise mines in China have been collected and compared with those in Jiahu site.All the samples have been studied through the Xray diffraction, petrographical comparison and isomorphic replacement in turquoise minerals. The result indicates that the turquoise in Jiahu site is quite different from all of the three modern mines on two aspects as follows: (1)the mineral assemblage of the surrounding rock; (2)the isomorphic replacement in turquoise mineral.The conclusion of our research is that the provenance of the turquoise in Jiahu site is not located in all of the three modern turquoise mines.
