Summary: During ODP Leg 104 a 900 m thick sequence of volcanic rocks was drilled at Site 642E on the Voring Plateau. It was subdivided into an Upper and a Lower series separated by 7 m of estuarine volcaniclastic and epiclastic rocks. The Upper series comprises transitional-type mid-oceanic ridge tholeiites with chemical affinities to the Faeroes and E Greenland plateau basalts and to Recent basalts from transitional segments of the mid-Atlantic ridge such as the Reykjanes ridge. The magmas are interpreted as having been derived from a secondarily LIL-element enriched, primarily strongly depleted mantle source. The Lower series contains 13 peraluminous dacite flows representing melts of upper crust metasedimentary rocks such as shales and greywackes.
