摘要
摘要本文初步报道了在波兰苏台德地区首次发现的正方晶11C磁黄铁矿(Fe(1-x)S)。在Góry Sowie地块Michałkowa Walim附近的一个典型伟晶岩产地发现了含磁黄铁矿的二辉石辉长岩样品。根据显微方法，磁黄铁矿与镍黄铁矿、黄铜矿、铬铁矿、钛铁矿、革辉云母、磁铁矿、黑云母、镁角闪石、斜黄铁矿、刺辉石和滑石伴生。x射线衍射(XRD)结果表明，磁黄铁矿具有正交11C结构，表征为:a = 3.433(9) Å， b = 5.99(2) Å， c = 5.7432(5) Å， β = 90º，d102 = 2.06906 Å。Mössbauer研究证实了XRD数据。磁黄铁矿有3个六分体，超细参数值分别为A六分体30.8 T、B六分体27.9 T、C六分体25.8 T，为正交结构，成分接近Fe10S11, x = 0.0909
Orthorhombic 11C pyrrhotite from Michałkowa, Góry Sowie Block, The Sudetes, Poland – preliminary report
Abstract This study provides the preliminary report about first occurrence of orthorhombic 11C pyrrhotite (Fe(1-x)S) from the Sudetes, Poland. Samples of pyrrhotite-containing two-pyroxene gabbro were found in a classic pegmatite locality in Michałkowa near Walim in the Góry Sowie Block. Based on microscopic methods, pyrrhotite is associated with pentlandite, chalcopyrite, chromite, ilmenite, gersdorffite, magnetite, biotite, magnesiohornblende, clinochlore, lizardite and talc. X-Ray diffraction (XRD) indicate that pyrrhotite has orthorhombic 11C structure and it is characterized by: a = 3.433(9) Å, b = 5.99(2) Å, c = 5.7432(5) Å, β = 90º and d102 = 2.06906 Å. Mössbauer studies confirmed the XRD data. Pyrrhotite has three sextets with hyperfine parameter values 30.8 T for sextet A, 27.9 T and 25.8 T for sextets B and C respectively, indicating orthorhombic structure, the composition near Fe10S11 and x = 0.0909
