利用能量色散X射线荧光光谱法(energy disperse X-ray fluorescence,EDXRF)对浙江嵊州小黄山与河南舞阳贾湖两处新石器时代前期遗址出土陶器的主量元素化学组成进行了分析测定。结果显示,这两处遗址出土陶器的化学组成地域特征明显,与贾湖遗址相比,小黄山遗址陶器具有我国南方陶瓷器普遍存在的"高硅低铝"的特征。同时,小黄山遗址早中晚三期陶器的化学组成未发生明显变化,表明其制陶原料来源与原料加工方式较为稳定,其陶器质量得以逐期提高主要是由于其烧成工艺不断进步的原因;贾湖陶器的化学组成从早到晚则发生了明显改变,这种变化的产生是由于随着时间推移,贾湖先民越来越多地在陶器胎料中加入大量的羼和料以改善陶器的使用性能所致。上述结果也表明,我国新石器时代前期不同地区因各自地域环境的差异,其陶器生产工艺的提高可能存在不同的演进方向。
The major elements in the early neolithic potteries unearthed from Xiaohuangshan site,Zhejiang Province and Jiahu site,Henan Province were determined by energy disperse X-ray fluorescence(EDXRF).The results show that the chemical compositions of the potteries from these two sites possess obvious regional features respectively.Compared with the specimen from Jiahu site,the potteries from Xiaohuangshan site have the common feature of ancient Chinese southern ceramics with high silicon and low aluminum contents.Simultaneously,the chemical composition of Xiaohuangshan pottery samples nearly unchanged from its early stage to the last stage.This phenomenon indicates that the source of the ceramic raw materials of Xiaohuangshan site was stable,and the continuous improvement of its pottery quality was mainly due to the progress in sintering techniques.However,the chemical composition of Jiahu potteries changed a lot in its three different periods.This change occurred because a large number of admixtures were added to the pottery bodies to improve their operating performances.These results also show that the improvements of pottery making techniques in different Chinese areas may have their own evolution directions respectively for the different geographical environments.
