四川汉源麻家山遗址出土陶器的科技研究

SCIENTIFIC STUDY ON THE POTTERIES EXCAVATED FROM MAJIASHAN SITE,HANYUAN COUNTY,SICHUAN PROVINCE

利用各种现代分析测试手段,分析了四川汉源县麻家山遗址出土的陶器的元素组成、物相组成等。实验表明,四川汉源县麻家山遗址出土的夹砂陶和泥质陶,Na2O、MgO、Al2O3、SiO2、K2O、CaO、TiO2、Fe2O3等主、次量元素含量差别不大,说明它们所用原料可能是相同的。从XRD与EDXRF的测试结果分析,夹砂陶的物相主要为石英、长石和云母。从因子分析的散点图可以看出,这批陶器同其他遗址出土陶器相比,具有明显的产地特征。其中一片成分特殊的陶器很有可能是由于先民们的经济文化交流或其他原因流传至此地。

Chemical concentration and phase component of the potteries excavated from Majiashan Site, Hanyuan County, Sichuan Province, were analyzed by some analyzing techniques. The result showed that the clay pottery and sand mixed pottery were similar in the concentrations of Na2O, MgO, Al2O3, SiO2, K2O, CaO, TiO2, Fe2O3, which indicated that they had used same raw material. The main phase components were quartz, feldspar and mica according to the result of XRD and EDXRF. The potteries had obviously provenance characteristics compared with other one in the scatter diagram, while a particular pottery could be traded from other region.
