Heavy rare-earth element enrichment in Archean felsic veins

¹ School of Geography and Geology, College of St. Paul and St. Mary Cheltenham, Gloucestershire GL50 2RH, England

Examples of heavy rare-earth element (REE) enrichment are described from granitic and trondhjemitic veins from the Lewisian complex at Scourie and Gruinard Bay. The observed enrichment results from the accumulation of phases rich in heavy REE, such as garnet, zircon, and allanite, during the emplacement of the veins and is probably controlled by filter-press fractionation. The melt composition exerts a strong influence on the partitioning of the heavy REE into these phases; therefore, heavy REE enrichment may only be seen in high-silica melts.
