Greenlandite[edit]

Attractive greenish-colored gneisses in southwestern Greenland that contain the minerals fuchsite (green) and quartz (gray) have been informally called greenlandite. Fuchsite is a chromian muscovite mica (K(Al,Cr)2AlSi3O10(OH,F)2 - potassium chromium hydroxy-fluoro-aluminosilicate); it is typically encountered in schistose rocks.

Greenland greenlandite is part of a 3.8 billion year old, highly metamorphosed succession of rocks. These represent the oldest known supracrustal rocks on Earth — Preceding unsigned comment added by Giacomo albertini (talk • contribs) 15:31, 14 May 2016 (UTC)[reply]

This list is based on the IMA-CNMNC Master List (International Mineralogical Association); no rocks, mostly valid minerals. --Chris.urs-o (talk) 15:52, 14 May 2016 (UTC)[reply]
