ABSTRACT
Fourteen rare-earth elements (REE) have been determined in metavolcanics and metagabbros from the island of Leka, Norway. The overall REE content of these rocks ranges from about 3 ppm, with strong light REE depletion, for the metagabbros to 170ppm with light REE enrichment, for porphyritic greenstones and pillow lavas. Based on regional geological features, lithology, and the REE abundances it is concluded that rocks of the island Leka constitute a part of an ophiolite complex.
