秦始皇陵二号坑兵马俑原料产地的中子活化分析

Neutron Activation Analysis on Source of Raw Material of Terracotta Warriors and Horses in No.2 Pit of Qin Shihuang's Mausoleum

选取19个秦始皇陵二号坑兵马俑样品和20个秦陵附近粘土样品,进行中子活化分析(NAA),测定每个样品中32种元素的含量,并将NAA数据进行模糊聚类分析,得到动态聚类分析图.结果表明,二号坑兵马俑样品与秦陵附近粘土样品关系密切,二号坑兵马俑的原料产地及烧制窑址可能在秦陵附近.另外,还初步研究了秦陵封土、二号坑的夯土、回填土与秦陵附近粘土的关系.

32 trace element contents in each sample are measured by neutron activation analysis for the selected that 19 samples of terracotta warriors and horses from No.2 pit of Emperor Qin Shihuang's Mausoleum, 20 samples clay nearby Qin's Mausoleum and 2 samples of Yaozhou porcelain bodies. The trend cluster analysis diagram is obtained after sortting the data. The results show that the samples from the No.2 pit of Emperor Qin Shihuang's Mausoleum have a close relationship with the clay samples from the neighborhood of the Mausoleum. Consequently, the source of raw materials of the terracotta warriors and horses may come from some places nearby the Mausoleum, the kiln sites may be also neighborhood of the Mausoleum. In this article there is also a preliminary study on the relationship between the sealing earth of the Mausoleum, rammed earth and backfill of the No.2 pit and the clay from the nearby place.
