“…It provided information on the electronic state of iron at crystallographically well identified positions, e.g. in almandine Fe3AlaSi30i2 and andradite Ca3Fe2Si30i2 (BANCROFT et al 1967;MARFUNIN et al 1967). DOWTY (1971) and BURNS (1972) suggested interpretations of 57 Fe spectra at 298 Κ from titanium andradites with complex cation distributions.…”

“…Notably, 57 Fe-Mössbauer and 63,65 Cu-NQR properties of bornite are not clear at present. Some previous Mössbauer studies show a singlet line at room and lower temperatures [8,9] with isomer shift IS = 0.41-0.47 mm/s [9,10]. At the same time, other data show a Mössbauer doublet with IS = 0.39 mm/s and quadrupole splitting QS ≈ 0.22-0.26 [11,12].…”

“…Early in our analyses, the pink phase was determined to be a pyralspite garnet and it was decided to continue the analyses since there are very little data on the Fe 2 § ion in the dodecahedral site of garnets and further since there is some interest in the crystal chemistry of this site in terms of site preference and crystal field stabilization energies. Thus far, only four 57Fe M6ssbauer or nuclear gamma-ray resonance (NGR) investigations of garnets containing dodecahedral Fe 2+ ions have been reported (Marfunin et al, 1967;Bancroft, Maddock, and Burns, 1967;Prandl and Wagner, 1971;Lyubutin and Dodokin, 1971). In these studies, however, the garnets investigated contained little or no manganese, and it is of interest to see what effect the manganese ion has on the crystal chemistry of the dodecahedral site as revealed by the 57Fe hyperfine interaction parameters.…”
