铅同位素组成在古陶产地判别中的应用

Discrimination of the production sites of ancient pottery by using lead isotopic composition

对铅同位素组成在鉴别古陶产地上的应用进行了探讨。对采自于河南省贾湖和西山两新石器时代遗址的古陶样品进行了铅同位素组成分析,大部分贾湖样品的铅同位素原子数比^(206)Pb/^(204)Pb为18.0—18.4,^(208)Pb/^(204)Pb为38.4—38.8,而大部分西山样品的铅同位素原子数比^(206)Pb/^(204)Pb为18.6—18.8,^(208)Pb/^(204)Pb为38.7—39.1。因此,对某些产地的古陶,铅同位素组成是鉴别其产地的有力工具。

Discrimination of the production sites of ancient pottery by using lead isotopic composition is discussed in this paper. We have determined the lead isotopic compositions of ancient pottery from the Jiahu and Xishan sites, Henan Province. Most of Jiahu pottery show 206Pb/204Pb of 18.0 to 18.4 and 208Pb/204Pb of 38.4 to 38.8, while most of Xishan pottery show 206Pb/204Pb of 18.6 to 18.8 and 208Pb/204Pb of 38.7 to 39.1. Therefore, the lead isotopes are useful in discriminating the production sites of the ancient pottery in some cases.
