摘要
为尝试比较汞同位素分馏数据来跟踪朱砂矿源,对成都市青白江区双元村战国墓地11个墓中的朱砂样本进行汞同位素测定。汞同位素分馏值彼此相似,应来自同一矿源。δ202Hg值从-1.18‰到-0.84‰不等(均值-1.010‰,标准误差0.105‰,样本数11个),和已发表的其他矿源汞同位素分馏值均存在差异。通过数据比较,可知成都青白江区双元村墓地不同墓中的漆器朱砂颜料汞同位素质量分馏值分布集中,极有可能来自同一矿源。如对周边地区朱砂矿进行汞同位素分馏值测量,有可能找出该墓地的矿源。
The mercury isotopic compositions of 11 cinnabar samples collected from tombs at Shuangyuan Village,Qingbaijiang District,Chengdu,were determined.The results show a similar isotopic fractionation,ranging from-1.18‰to-0.84‰(avg.-1.010‰,S.E.0.105‰,n=11).Compared with published data of some cinnabar ores,these fractionation numbers are different.In the future,these numbers may help to identify possible mineral sources of the Shuangyuan Village samples if mercury isotopic compositions of nearby cinnabar mines are analyzed.
