Picrites from Nuussuaq Peninsula and Qeqertarssuaq (Disko) Island, West Greenland, preserve trace element and isotopic signatures reflecting the composition of the Icelandic plume head. Os isotope ratios are low ( 187 Os/ 188 Os (i) =0.1272–0.1371) in terms of global plume related magmatism, and thi...
