记录了三种含铁锑矿物的~（57）Fe穆斯堡尔谱。成分为FeSb_2O_4的钙钛矿含有Fe ~（2+）。121 Sb穆斯堡尔谱仅显示Sb 3+的存在。57 Fe穆斯堡尔谱对应于在这项工作的过程中通过固态反应合成的相同组成的材料的记录。结果表明，Fe 20 Sb 16 O 48 S4型水锰矿中Fe ~（2+）：Fe ~（3+）为1：3.35，与晶体结构测定结果及水锰矿的Fe 42 + Fe ~（163）+Sb 16 O 48 S4型相一致。成分为Fe 12 Sb 12 O 32 S 2的镁硅沸石含有比例为1：2.12的Fe 2+和Fe 3+，并且也与结构特征一致，可以用公式表示为Fe 42 + Fe 83 + Sb 123 + O 32 S 2。
Iron-57 Mossbauer spectra have been recorded from three minerals containing both iron and antimony. Schafarzikite of composition FeSb2O4 contains Fe2+. The 121Sb Mossbauer spectrum shows only the presence of Sb3+. The 57Fe Mossbauer spectrum corresponds with that recorded from a material of identical composition synthesised by a solid state reaction during the course of this work. Apuanite of formulation Fe20Sb16O48S4 contains both Fe2+ Fe3+ in the ratio 1:3.35 The result is consistent with crystal structure determinations and the formulation of apuanite as Fe42+Fe163+Sb16O48S4. Versiliaite of composition Fe12Sb12O32S2 contains Fe2+and Fe3+ in the ratio 1:2.12 and, also consistent with structural characterisations, can be formulated Fe42+Fe83+Sb123+O32S2.
