【摘要】 <正> 锡铁山石(Fe³⁺[SO₄][OH]·7H₂O)是一种高铁硫酸盐矿物,产于青海柴达木盆地北缘锡铁山铅锌矿床氧化带中。它作为一种新矿物已有报道,本文仅介绍它的穆斯鲍尔效应和电子顺磁共振研究结果,以补充该矿物一些新的资料。 将矿物晶体与纯淀粉按1:5的比例混匀研细,在钢模内压成片状吸收体,其有效厚度约为4mg/cm²。等加速穆氏谱仪,用α-铁的六线谱进行速度标定。⁵⁷Co（Pd）放射源,约10毫居里。更多还原

【Abstract】 Xitieshanite, which was found not long ago in Qinghai, China.,is aferric sulfate mineral.Its Mossbauer spectrum shows a single doublet patternwith the typical Mossbauer parameters of Fe³⁺: I. S. = 0.36 mm/s and Q. S.=0.58mm/s; the large line width Γ=0.50 mm/s might be indicative of someinhomogeneity in the crystal of xitieshanite. EPR measurements of the singlecrystal yielded the isotropic spectra with each a broad line（g ≈ 2 and the linewidth is about 1000 G） given by Fe³⁺.更多还原
