(Web2) FGH afghanite a hydrous hexagonal feldspathoid mineral of the cancrinite group.
The main mineral compositions of Bayer red mud are cancrinite, hydrogrossular, calcite, and xonotlite.
According to the X-ray diffraction, the Bayer red mud is comprised of cancrinite, hydrogrossular, tilleyite, calcite, and xonotlite; the main chemical constituent was Si[O.sub.2] (accounting for 22.35%), followed by 20.80% of [Al.sub.2][O.sub.3], 18.51% of CaO, 8.83% of [Na.sub.2]O, 7.73% of [Fe.sub.2][O.sub.3], and a small amount of mixture of K2O, MgO, Ti[O.sub.2], and S[O.sub.3].

Phonolites are typically microphyric to hypocrystalline with alkali feldspar phenocrysts or microphenocrysts ([Or.sub.43-83]), nepheline ([Ne.sub.67-79]), occasionally altered to cancrinite, acmitic clinopyroxene (acmite up to 63wt%), and ferroedenite-ferropargasite amphibole.

These rocks contain mineral 'nepheline' as their major component along with other feldspathoidal minerals, like, cancrinite and sodalite [1, 12, 13, 17].

This transition zone is enriched by grayish white fibrous lorenzenite and contains pods of brown cancrinite.
XRD showed that muscovite, hematite/ maghemite, goethite, quartz, calcite, anatase, DSP (as identified here has a zeolite type structure and resembles sodalite and cancrinite; Thornber and Hughes 1992), and gibbsite were the main crystalline minerals present in the red muds.
