The Shanpaolü from Zhejiang Province belongs to non-pyrophyllite-type species of Qingtian Stones. With its fine quality and beautiful color, Shanpaolü becomes a new variety of carving stone. In this paper, the authors made some experiments by such means as EPMA, XRD, XED and IR differential thermal analysis, focusing on the components of Shanpaolü. The results show that the main composition of Shanpaolü is dense directional alignment sericite, containing a small amount of quartz, andalusite etc. with a certain amount of structural water. The influence of these components on the quality of Shanpaolü was also discussed.
