Remanent magnetic directions of some dykes from southern West Greenland

Depleted spinel harzburgite xenoliths in Tertiary dykes from East Greenland: Restites from high degree melting

A new collection of mantle xenoliths in Tertiary dykes from the Wiedemann Fjord area in Southeast Greenland shows that this part of the central Greenland craton is underlain by highly depleted peridotites. The samples are mostly spinel Ž . harzburgites with highly forsteritic olivines Fo , average Fo . This, together with unusually high modal olivine 87– 94 92.7 Ž . contents 70–)95% , places th...

Lake-catchment interactions with climate in the low Arctic of southern West Greenland

Establishment of a 3.83-Ga magmatic age for the Akilia tonalite (southern West Greenland)

A recurring challenge to ion microprobe U^Pb zircon geochronology has been to discriminate between preservation of original igneous zircon populations and inherited grains. This has proved particularly problematic in studying the polyphase metamorphic rocks that dominate Early Archean gneissic terranes. For example, differing interpretations exist for the origin of complex zircon populations in...

Population structure of West Greenland narwhals

The hypothesis that different populations of narwhals in the West Greenland area exist has been tested by different biomarkers (metal and organochlorine concentrations, stable isotopes and DNA). Samples of muscle, liver, kidney, blubber and skin tissues of narwhals from West Greenland have been analysed for heavy metals, organochlorines, stable isotopes and DNA. The obtained results of metal co...
