Overview

Kaersutite is a dark brown to black double-chain calcic titanium-bearing amphibole mineral with formula: NaCa2(Mg3Ti4+Al)(Si6Al2)O22(O)2. Ferro-kaersutite is the divalent iron-rich endmember of the kaersutite group, with the iron replacing magnesium in the structure. Kaersutite occurs as phenocrysts in alkalic volcanic rocks, in nodules of peridotite and gabbro in alkalic basalts, and in syenites, monzonites, and carbonatite tuffs. Mineral associations include titanian augite, rhoenite, olivine, ilmenite, spinel, plagioclase, and titanian pargasite. It was first described in 1884 and is named for Qaersut (formerly Kaersut), Umanq district in northern Greenland.
