| 摘 要： | 除硅铁钡矿之处，性石是迄今仅知的另一种含有平面四配位Ｆｅ＾２＋的矿物，异性石晶体样品为玫瑰色，透明，有油脂光泽，取自一花岗岩标本，异性石中平面四配位Ｆｅ＾２＋的穆斯堡尔参数：化学位移＝０．７８５（ｍｍ／ｓ）（相对天然铁），四极矩分裂＝０．４１９（ｍｍ／ｓ），明显地低于大多数硅酸矿物中的Ｆｅ＾２＋，但和硅铁钡矿的Ｆｅ＾２＋十分相近，本文对硅酸盐矿物Ｆｅ＾２＋的穆斯堡尔参数与配位数之间的关系做了讨论。

| Abstract: | In addition to gillespite, eudialyte is another kind of mineral so far knowm, in which Fe2+ is square planar coordinated. The eudialyte sample, glossy and transparent in nossy, was found in a specimen of alkali granite. Mossbauer parameters of the square planar coordinated Fe2+ in eudia lyte are:I. S. =0. 785mm/s (to natural iron)Q. S =0. 419mm/smuch smaller than those of Fe2+ in most silicate minerals, but similar to those in gillespite. The relationship between the Mossbauer parameters and the coordination of Fe2+ in silicate minerals are discussed as well. |
