河曲坪头遗址龙山时期陶器及其制陶原料的化学成分分析

Chemical analysis of pottery and clay raw materials from the Longshan period at the Pingtou site in Hequ county,Shanxi province

为了对山西省忻州市河曲坪头遗址出土的龙山时期的陶器以及制陶原料中的粘土原料的种类和来源进行相关探讨,利用ICP-OES对出土的陶器、坯料,以及遗址附近采集的土样进行了化学成分测试,并使用SPSS软件对分析结果进行了降维处理和主成分分析。结果显示:坪头遗址不同质地的陶器陶土原料相同,只是在钙含量方面存在细微差异。制作陶器所用的粘土原料很可能取自附近的红色古土壤层。该遗址是古人在当地制作陶器的一个场所。

The chemical compositions of the clay from excavated pottery,raw materials and semi-finished products from the Pingtou site,as well as soil samples around the site,were analyzed by inductively coupled plasma atomic emission spectroscopy（ ICP-AES）. Through principal component analysis of the data by SPSS18. 0,it was deduced that the clay material composition of various types of pottery is the same,although with slight differences in the concentration of calcium. The clay raw materials used to make the pottery were dug from the red soil layers near the site. The Pingtou site was an ancient local pottery production site.
