Сажетак
Four macroscopically visible B–E (rim) zones, within a large natural ferric grossular garnet of Grs58–64Adr36–42 Sps2 composition, are described by means of Rietveld refinements of the crystal structures in a series of six space groups, followed by com parative analysis of the R-values, site occupancy factors, and bond lengths and angles. The garnet crystallized in the rhombohedral R63c space group. Various polyhedral distortions and structural or derdis or dervariations between the zones studied are also described and discussed. The rhombohedral symmetry of the ferric grossular garnet analysed can be regarded as primary, residual strain being a secondary cause for its slight optical anisotropy.
