摘　　要：应用电子探针、化学分析、X射线衍射、红外光谱、拉曼光谱等分析手段对加良山寿山石进行了研究 ,结果表明其主要组成矿物是叶蜡石 ,并含有硬水铝石和石英 ,大部分叶蜡石以 2M型为主。该矿区为火山热液矿床 ,成矿明显分为早、中、晚 3个阶段 ,成矿温度 2 85～ 40 5℃ ,压力小于 0 .2 6GPa。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.
