Density

Does anybody know the density of Chlorite? If you do, please fix it.

Properties of Cholrite (from: http://www.spaceman.ca/mineral/index.php?ViewMineral=32) Class: Silicate Subclass: Phyllosilicate Hardness: 2 - 2.5 Density: 2.6 - 3.3 Streak: Greenish white to white Lustre: Vitreous to somewhat pearly, waxy, dull Colours: Greenish-black (typical) Crystal System: Monoclinic Cleavage: Perfect {001} Magnetism: None Reaction with HCl: None

Identification in hand sample: Colour and its low hardness are distinguishing characteristics.

Industrial / ecomonic uses: None, however chlorite schist sometimes does have ornamental uses.

endmember

I know and you know probably what 'endmember' means, (see line 2 of the article) but where is formal definition? regford 23:28, 21 January 2006 (UTC)[reply]

Clay minerals?

As far as I am aware, chlorite is not necessarily a clay mineral. It is mostly a metamorphic mineral, though I can see how chlorite minerals sometimes overlap, for instance in argillic alteration, with "clay" minerals such as kaolinite, etc. Thoughts? Rolinator 04:37, 6 October 2006 (UTC)[reply]

Very late to the party. It depends on whom you ask. Some mineralogy texts include it as a clay mineral; others do not. --Kent G. Budge (talk) 23:39, 6 January 2021 (UTC)[reply]

Obvious question? Maybe not.

Chlorite is ClO2. I read this whole article never saw any mention of chlorine at all. So why the name? RStillwater (talk) 02:56, 20 November 2008 (UTC)[reply]

The minerals of the chlorite group have nothing to do with chlorine. The name as noted in the article is from the Greek chloros for green, the typical color of the minerals. The disambiguation note at the top points to the chemical usage of the word - the ClO₂^- polyatomic ion. Vsmith (talk) 03:37, 20 November 2008 (UTC)[reply]

typo in Structure section ?

Inexpertly, the "Bructite layer" paragraph is missing a subscript of "3", for the (Fe³⁺,Mg³⁺)₃(OH)₆66.235.38.214 (talk) 12:21, 12 October 2012 (UTC)[reply]

Inexpertly, most ("chlorophyll green") Chlorites have the chemical structure: (MO)₅ C Q₃ W₄ — (MO W)₃, alloying Mafic oxides (Fe, Mg, Ni, Mn), Corundum, Quartz, and Water.66.235.38.214 (talk) 12:30, 12 October 2012 (UTC)[reply]

For sake of memorization, the above formula simplifies, first, to (MO W)₄ — (MO) C Q₃ — (MO W)₃; and then to (MO W)₄ — (MO Q) (C Q) (Q) — (MO W)₃. The middle members are Pyroxene, Aluminosilicate, and Quartz, in "solid solution" with "rusty water". 66.235.38.214 (talk) 09:33, 20 October 2012 (UTC)[reply]

Short description

Presently, the short description is "Phyllosilicates: non-swelling 2:1 clay (TOT) whose interlayer is occupied by a brucite, Mg(OH)2, bridge". I realize there are no hard and fast rules, but this seems a bit too elaborate to me. I would choose "group of claylike sheet silicate minerals" or "group of claylike phyllosilicate minerals" depending on your tastes. WP:Short description has some guidelines, though no hard rules. --Kent G. Budge (talk) 23:44, 6 January 2021 (UTC)[reply]
