摘要
摘要:陕西洛南河口遗址是目前我国发现最早开采绿松石的古矿遗址，它的发现为研究中国早期绿松石的来源提供了重要的信息。为探索河口古矿出产绿松石的去向，本文结合秦岭东部的其他现代绿松石产地矿样，利用铅和锶同位素比值法，试图初步建立我国中原地区绿松石产地的判别模型。主要实验结果如下：利用TIMS技术对秦岭东部陕西白河、湖北郧县、湖北竹山、陕西洛南、河南淅川这5个产地的绿松石矿石样品中的铅、锶同位素进行了检测，从而为分析和探索这5个产地绿松石各自的地球化学特征提供数据。实验发现来自同一产地样品的铅、锶同位素比值具有较好的一致性。绿松石的铅同位素比率（²⁰⁷Pb/²⁰⁸Pb）可以以比率值0.410为界分为2组。绿松石的锶同位素比率（⁸⁷Sr/⁸⁶Sr）可以按比率值0.7105、0.7145为界划分为3组。结合铅、锶同位素比值和锶含量数据，可以初步区分不同产地的绿松石原料。通过应用该模型测试二里头遗址出土绿松石文物的原料产地，结果表明，洛南河口古代绿松石采矿遗址应是二里头绿松石的原料产地之一。

Abstract:Hekou Mining site is the earliest turquoise mining site in China, until now, the discovery of which provides important information for studying on the origin of ancient turquoise. For tracing the whereabouts of turquoise ore from the Hekou site, this paper is in the purpose of establishing an initial identification model for differing turquoise origin in Central China, based on the isotopes ratio values of lead and strontium for turquoise samples from the five mines of Baihe Shaanxi(11 samples), Yunxian Hubei(9 samples), Zhushan Hubei(11 samples), Luonan Shaanxi(14 samples), Xichuan Henan(10 samples) in the east of Qinling Mountains. The lead and strontium isotopes ratio values for the samples were collected by Thermal Ionization Mass Spectrometry(TIMS), which offers data to find the geochemical features of the turquoise from these five mines. Preliminary results show that the samples from the same mine have a good consistency on their lead isotope ratio values. Furthermore, the modern turquoise can be divided into two groups with the lead isotope(²⁰⁷Pb/²⁰⁸Pb) ratio value boundary at 0.410. Referring to the strontium isotope(⁸⁷Sr/⁸⁶Sr) ratio values, turquoise samples can be parted into three groups according to the boundaries at 0.7105 and 0.7145. Finally, combining the isotope ratio values of lead and strontium with the strontium content, the model could be established to preliminarily distinguish the modern turquoise samples from the east of Qinling Mountains. When the model was performed on tracing the origin of three archaeological turquoise relics unearthed from the ash pit(2004VT85H290) of the Erlitou site, the result suggested that these turquoises should be from the Hekou mining site in Luonan.
