arfvedsonite การใช้
- Cummingtonite shares few compositional similarities with alkali amphiboles such as arfvedsonite, glaucophane-riebeckite.
- Glaucophane, crocidolite, riebeckite and arfvedsonite form a somewhat special group of alkali-amphiboles.
- The mineral specimens of aegirines, arfvedsonite and feldspars are some of the best in the world.
- The complex is noted for a wide variety of rare minerals and is the type locality for thirty minerals, including : aenigmatite, arfvedsonite, sodalite, eudialyte and tugtupite.
- Sodalite-syenites in which sodalite very largely or completely takes the place of nepheline occur in Greenland, where they contain also microcline-perthite, aegirine, arfvedsonite and eudialyte.
- Associate minerals include : microcline, nepheline, aegirine, lamprophyllite, lorenzenite, catapleiite, murmanite, arfvedsonite, sodalite, aenigmatite, rinkite, l鍁enite, titanite and titanian magnetite.
- Serandite has been found in association with aegirine, analcime, arfvedsonite, astrophyllite, eudialyte, fluorite, leucophanite, mangan-neptunite, microcline, nepheline, sodalite, and villiaumite.
- The lujaurites are distinguished from the rocks above described by their dark color, which is due to the abundance of minerals such as augite, aegirine, arfvedsonite and other kinds of amphibole.
- It occurs in association with quartz, narsarsukite, calcite, fluorite, ancylite, molybdenite, leucosphenite, lorenzenite, galena, albite, pectolite, apophyllite, leifite, microcline and arfvedsonite.
- It occurs in nepheline syenites and pegmatites in association with aegirine, nepheline, microcline, arfvedsonite, elpidite, loparite, eudialyte, astrophyllite, mangan-neptunite, lavenite, rinkite, apatite, titanite and ilmenite.
- Rocks of this group are known from Rio de Janeiro, Arkansas, Kola Peninsula ( in Russia ), Montana and a few other places ., In Greenland there are leucite tinguaites with much arfvedsonite, ( hornblende ) and eudialyte.
