Crocoite is commonly found as large, well-developed prismatic adamantine crystals, although in many cases are poorly terminated. Crystals are of a bright hyacinth-red color, translucent, and have an adamantine to vitreous lustre.
Chromite contains Mg, ferrous iron [Fe(II)], Al and trace amounts of Ti. [5] Chromite can change into different minerals based on the amounts of each element in the mineral. Chromite is a part of the spinel group, which means that it is able to form a complete solid solution series with other members in the
Chromitite with bronzite phenocrysts from Stillwater Igneous Complex. Chromitite is an igneous cumulate rock composed mostly of the mineral chromite.It is found in layered intrusions such as the Bushveld Igneous Complex in South Africa, the Stillwater igneous complex in Montana and the Ring of Fire discovery in Ontario.
In chemistry the term chromite has been used in two contexts. Under IUPAC naming conventions, chromate(III) is preferred to chromite. [citation needed] For compounds containing an oxyanion of chromium in oxidation state of +3; For other compounds of chromium(III) as a means of distinguishing a chemical species such as hexacyanochromite(III).
Discordant rock, one that cuts across the existing bedding: as in one of the main types of igneous intrusion, or as in the sedimentary clastic dikes; Discordant strata, rock layers with mismatches in the geologic record; Discordant coastline, when the bands of rock run perpendicular to the coast
The Cambridge Greek Lexicon is a dictionary of the Ancient Greek language published by Cambridge University Press in April 2021. First conceived in 1997 by the classicist John Chadwick, the lexicon was compiled by a team of researchers based in the Faculty of Classics in Cambridge consisting of the Hellenist James Diggle (Editor-in-Chief), Bruce Fraser, Patrick James, Oliver Simkin, Anne ...
The most common mineral inclusion in peridot is the chromium-rich mineral chromite. Magnesium-rich minerals also can exist in the form of pyrope and magnesiochromite. These two types of mineral inclusions are typically surrounded "lily-pad" cleavages. Biotite flakes appear flat, brown, translucent, and tabular. [16]
Stichtite is a mineral, a carbonate of chromium and magnesium; formula Mg 6 Cr 2 C O 3 (OH) 16 ·4H 2 O.Its colour ranges from pink through lilac to a rich purple colour. It is formed as an alteration product of chromite-containing serpentine.
