Based on such analytical means as EMPA, chemical analysis, XRD, IR and LRM, the authors have extensively studied Shoushan Stone from Jialiangshan in Fujian Province. The results show that Shoushan Stone in Jialiangshan area is a kind of rock mainly composed of pyrophyllite, diaspore and quartz. Most of the stones have perfect 2M type of pyrophyllite. The Shoushan Stone in Jialiangshan area was formed by hydrothermal activities and the ore_forming process can be divided obviously into three stages. The metallogenic temperature is about 285~405℃and the ore-forming pressure is lower than 0.26 GPa.
