4. Monazite in metasediments from Stensjöstrand : a pilot study
University essay from Lunds universitet/Geologiska institutionenAbstract : Monazit är ett Ree– och Th-bärande fosfatmineral som förekommer i vissa magmatiska och metamorfa bergarter. Mineralet är användbart för datering av den metamorfa utvecklingen och kan bidra till att yt-terligare karaktärisera metamorfosen i en bergart, detta genom att man undersöker zoneringar i kristallerna.
