西安半坡遗址祭祀坑析白物成份分析研究

Study on Unknown Component Analysis of a Pit for Sacrifice in Xi'an Banpo Sites

基于半坡遗址遭受可溶性盐分的侵蚀,采用传统的化学分析方法对其可溶性盐分进行了定性和定量分析,同时,用XRD对遗址土样的矿物成份也进行了分析,得出遗址表面析出的白色物质主要是硫酸钙晶体。

Based on the Banpo Sites disease problem, the soluble salt of sites soil samples component and content were analyzed in conventional qualitative and quantitative method. At the same time, its mineral compositions were characterized in XRD, too. As a result, the soluble salt of Banpo Sites is mainly gypsum.
