| 英文摘要 | Monoclinic astrophyllite from Kala Peninsula, Russia was investigated by Fe-57 Mossbauer effect. The Mossbauer spectra of the sample at 298 K, 180 K and 80 K were measured. Each spectrum of monoclinic astrophyllite consists of two Fe2+ and one Fe3+ quadrupole doublets. The distortion parameters, the variances of the octahedral bond angles sigma(2) and the normalized bond-length variation Delta for monoclinic astrophyllite were calculated. However, since a discrepancy between two distortion parameters exists, an assignment of the quadrupole doublet to iron at the specific site was not given. Temperature dependences of the isomer shift and the quadrupole splitting were presented and discussed. According to the ratio of ferric to total iron obtained by the Mossbauer effect and the mean value of f (Fe3+ (O)) /f (Fe2+ (O)), the chemical formula of monoclinic astrophyllite was rewritten. |
