A variety of Minerals
What is Narsarsukite?
Narsarsukite is a rare silicate mineral with chemical formula Na2(Ti,Fe)Si4(O,F)11 or Na4(Ti,Fe)4Si8O204. It was first described in 1900 for an occurrence in the Narsarsuk pegmatite in the Ilimaussaq intrusive complex of West Greenland. It has also been reported from a syenite which intruded limestone in the Sweetgrass Hills, Montana, and within hornfels and marble xenoliths in the alkalic intrusive of Mont Saint-Hilaire, Quebec. It occurs associated with aegirine, microcline, albite, elpidite, epididymite, taeniolite, pectolite, calcite, galena and quartz.
