Named for the type locality at the Östanmoss Mine in Norberg, Sweden. Norbergite is a rare mineral found in localities that in addition to Sweden include Finland, Scotland, the United States and Italy among a few others. It occurs in limestones and dolostones in zones of contact metamorphism where plutonic rocks and/or pegmatites have introduced fluorine. Can fluoresce a pastel canary-yellow under shot-wave ultraviolet light.

Named for the discoverer of the mineral, Charles Normand. A rare mineral that occurs at the type locality at Mont Saint-Hilaire in Quebec, Canada in cavities and as vesicule fillings in nepheline syenite along with microcline, catapleiite, and eudialyte. Additional localities include in the Khibiny and Lovozero massifs in the Kola Peninsula of Russia as large crystals in alkaline pegmatites, as well as in Spain, Morocco, Guinea, Greenland, and Brazil.

Named for Keith Norseth who was an engineering geologist as the Westvaco trona mine in Wyoming, USA and assisted greatly in mineralogical studies. Norsethite is a rare mineral that occurs authigenically in and under the Green River Formation in the United States and is also found in carbonatites as a primary mineral as well as in hydrothermal deposits that have undergone metamorphism. Localities for Norsethite include in other US localities, Canada, Brazil, Russia, China, Scotland, Sweden, and Namibia among a few others. Norsethite can fluoresce dark red under ultraviolet light.
