Monazite cathodoluminescence - A new tool for heavy mineral analysis of siliciclastic sedimentary rocks

Detection of monazite in heavy mineral separates from Triassic sandstones of E-Bavaria allows us to reconstruct different crystalline source areas (Bohemian Massif, Erzgebirge). Altogether, the monazites from these areas show the same CL-behaviour like those from other crystalline areas (Dora Maira Massif) and from placers (Bahia/Brazil, Taiwan). These investigations underline the considerable potential of the cathodoluminescence technique for heavy mineral analysis and specifically for the distinction of minerals with similar optical properties.
