Using petrographic analysis and major and trace element analysis,systematic examination and comparison were conducted on white pottery samples unearthed from four large Longshan culture sites in the western part of the Haidai region,namely Chengziya,Dinggong,and Liangchengzhen and Yaowangcheng to the east.Through this analysis,in addition to geological background surveys and research,this study reveals that most raw materials for white pottery samples from the eastern and western groups of sites in the Haidai region were probably locally obtained.While high-quality clay was more easily accessible at the Chengziya and Dinggong sites,white pottery from the Liangchengzhen and Yaowangcheng sites showed a diversity of sources,with some high-quality white pottery likely imported from more distant regions to the west.This indirectly reflects the existence of wider social networks and even stronger political and military power within political groups associated with these two sites.
