Abstract

We have examined archived drill-cores of intrusive carbonate rocks from the Korsnas Pb-REE deposit in western Finland. The samples were studied for their major and trace element compositions, and isotope ratios of C and O. The deposit was operated in the 1960's and 70's, yielding a total 36 000 tons of Lanthanide concentrate as a by-product of Pb beneficiation. The origin of the dike swarm that hosts the mineralization, whether related to hydrothermal, late-stage igneous, or carbonatitic processes, has remained controversial, however. Our new results set geochemical constraints to the origin of these rocks, and will be used as a basis for further studies on the deposit that represents a mile stone in the Finnish mining history, and one of the first large-scale rare earth element (REE) mines in Europe.
