摘　　要：本文采用高温熔融体热处理结晶的方法合成了含亲硫元素Zn的云母K_(1.66)Ba_(0.17)(Mg_3Zn_2)(Si_8O_20)F_4,其晶胞参数为α=0.525nm,b=0.911nm,c=2.005nm,β=91.28°。这种新型云母的合成在矿物学和地球化学上具有理论意义。A new type of mica containing the sulphurphilic element Zn, whose chemical formula is K_(1.66)Ba_(0.17)(Mg_3Zn_2)(Si_8O_(20))F_4 and parameters: α=5.246(?),b=9.108(?), c=20.049(?), and β=91.28°, has been synthetized by letting mica crystallize from a high temperature melt using the thermal treatment method. The synthesis of this new type of mica is of great significance both in mineralogy and in geochemistry.
