About Grossular-Katoite SeriesHide

Crystal System:
Isometric
Series Formula:
Ca3Al2(SiO4)3 to Ca3Al2[◻(OH)4]3
A series between Grossular and Katoite

Although no longer an IMA-approved species, Hibschite is an informal intermediate composition within the series.
See also hydrogrossular.

1Sør Rondane Mountains, Queen Maud Land, East Antarctica, AntarcticaSample: Green (tsavorite) porphyroblast Method: Microprobe
2Itrafo, Ampanivana area, Andrembesoa, Betafo District, Vakinankaratra, MadagascarSample: Brown-green crystal. Method: JEOL JXA-8200 electron microprobe in wavelength-dispersive mode under the following conditions: 15 kV accelerating voltage, 15 nA beam current, and count times of 60 seconds on peaks and 30 seconds on the background. The following standards were used: natural grossular (for Si and Ca),banorthite (Al), fayalite (Fe), olivine (Mg), rhodonite(Mn), omphacite (Na), ilmenite (Ti), K-feldspar (K), and pure V and Cr for those elements. The raw data were corrected for matrix effects using a conventional ΦρZ routine in the JEOL software package.
3Jeffrey Mine, Val-des-Sources, Les Sources RCM, Estrie, Québec, CanadaSample: Light brown and pale orange coloured crystal. Method: Electron-probe micro-analyses were performed with a HITACHI X-569S microprobe operating at an accelerating voltage of 15 kV and a beam current of 15 nA
4Wazuka-cho, Soraku District, Kyoto Prefecture, JapanSample: An intermediate grossular, almandine, spessartine composition from a metamorphosed marl.
5Bellecombe, Châtillon, Aosta Valley, ItalySample: Red euhedral grossular (hessonite) crystals associated with clinochlore from rodingite. Method: Quantitative chemical compositions, line scans, backscattered electron (BSE) images, and X-ray elemental maps were collected with a JEOL JXA-8200 WD-ED electron-probe microanalysis (EPMA). The JEOL operating program on a Solaris platform was used for ZAF (atomic number, Z; absorption, A; fluorescence, F) correction and data reduction
