Magnesiochromite

This page is currently not sponsored. Click here to sponsor this page.
Formula:
MgCr2O4
Mg may be partially replaced by divalent Fe, and Cr by Al and trivalent Fe.
Colour:
Black, deep red
Lustre:
Greasy, Metallic, Sub-Metallic
Hardness:
Specific Gravity:
4.1 - 4.3
Crystal System:
Isometric
Member of:
Name:
Named by Antoine François Alfred Lacroix in 1910 in allusion to the composition, containing MAGNESIum and its relationship to CHROMITE. The mineral was originally named magnochromite by G. M. von Bock in 1868.
Isostructural with:
Spinel Group, Cr subgroup. Chromite-Magnesiochromite Series and Magnesiochromite-Spinel Series. It forms a complete solid solution series with many other members of the group. It is the magnesium analogue of zincochromite, cochromite, manganochromite and chromite and the Cr analogue of spinel and magnesioferrite.

It usually contains ferrous iron [Fe(II)], ferric iron [Fe(III)], and Al. "Ferritchromite", i.e. Fe(III) substitutions for Al and Cr, usually in grain rims, may give high total Fe and a false chromite identification, whereas Fe(II)> Mg is the actual deciding factor in the species designation for chromite. Magnesiochomite is about twice as common as chromite.

Much of the mineral referred to as "chromite" in geological and petrological papers and mining statistics is magnesiochromite. The Fe-dominant species chromite may be subordinate to magnesiochromite in many "chromite" deposits, chromitites, and other "chromite"-bearing rocks.

Note: Chromite, that is near end-member, has a higher specific gravity than near end-member magnesiochromite.
