Twenty - four trace elements in twenty - eight greenish - white Song - Yuan dynasty porcelain fragments unearthed in the Three Gorges were analyzed by (neutron activation analysis (NAA) to determine their sites of production. Twenty porcelain pieces previously dated to a similar age, with known sites of origin, were also analyzed by NAA. The data obtained were analyzed by SPSS, a statistical software package. It was found that the rare earth element contents in porcelain produced in Jiangxi are significantly different from those produced in other provinces, such as Fujian, Anhui and Hubei. The Rb, Cs, Hf and Th compositions in these porcelains are also obviously different from site to site. Among the porcelains unearthed in the Three Gorges, all have trace element characteristics similar to those produced in Jingdezhen, except for two pieces, labeled Rongyang5 and Tushanyao5. These results suggest that most of the greenish - white porcelain fragments unearthed in the Three Gorges were very likely produced in Jingdezhen, Jiangxi.
