【摘要】 <正> 锶磷钙铝矾(Strontium Woodhouseite)是磷锶铝矾(svanbergite)和磷钙铝矾(woodhouseite)之间的过渡矿物。国外已先后发现该系列矿物的两个湍元,本文为与其他文献不同的典型的中间矿物。 作者1980年在研究苏州市阳山东白善岭高岭土矿区的物质组成时发现了该矿物。经等离子发射光谱定性分析,该矿物的锶元素含量很高,嗣后进行了x射线粉晶照相,电子探针和能谱定量分析,确定为锶离子比值略低于钙离子比值的锶磷钙铝矾。更多还原

【Abstract】 The fibrous strontium woodhouseite is different in the ion-ratio of Sr and Ca from neither the end member nor other interim minerals of svanbergite [SrAl3CPO4) (SO4)(OH)6]- woodhouseite [CaAl3(PO4)(SO4)(OH)6] system. The structure formula, based on the mean component by the energy spectrum of scanning electron microscope, is K0.059(Ca0.639, Sr0.443)1.082Al2.984(P1.488, S0.549)O8.148(OH)6. The stronger liners in X-ray powder pattern are. 5.741(5), 3.465(5-6), 2.949(10), 2.160(8), 1.871(9), 1.748(9), 1.186(5), 1.160(5). The fibrous strontium woodhouseite is different from the relational minerals discovered so far in form of minerals, habit of crystals, and some optical-physical property etc. The strontium woodhouseite belongs to the type of altered mineral of low temperature, its associated minerals, except Kaolinite, are marcasite and alumite.更多还原
