Benzanol Garnet | C32H23N5O7S2 - PubChem

Congo corinth (acid form) is an aminonaphthalenesulfonic acid that is 3,3'-[[1,1'-biphenyl]-4,4'-diylbis(diazene-2,1-diyl)]di(naphthalene-1-sulfonic acid) in which the two hydrogens at the 4-positions on the naphthalene rings are placed by amino and hydroxy groups. The disodium salt is the histological dye 'Congo corinth'. It has a role as a fluorochrome and a histological dye.

In terms of chemical bonding in silicate garnets it has been shown, using calculated bond valences, that Ca-O bonding in andradite is stronger than Fe 2+-O bonding in almandine and Mg-O bonding in pyrope (Armbruster and Geiger 1993). Thus, the OH bond in andradite will be weakened compared to that of the latter two garnets.

Garnet | Geoscience Australia

Most garnet forms when a sedimentary rock with high aluminium content, such as shale, is metamorphosed (subjected to heat and pressure). The high heat and pressure breaks the chemical bonds in the rocks and cause minerals to recrystallise. The new minerals, that form, such as garnet, are more stable in those conditions.

Garnet can also be a major host for trace elements in peridotite xenoliths, especially in harzburgites. A large data set was recently summarized by Griffin et al. (1999a).The abundances of manganese and nickel in peridotitic garnets change due to T-dependent partitioning with coexisting olivine (Sachtleben and Seck, 1981; Griffin et al., 1989; Smith et al., 1991; Canil, 1999).
