Geochemical methods to advance knowledge on the early Earth require supplies of well-preserved >3600 Ma rocks and minerals (e.g. zircon). One of the most important resources for these are small domains within high metamorphic grade Palaeoarchaean gneisses in the Archaean Craton, southern West Greenland. In the Nuuk region these gneisses occur as two terranes (totalling ∼3000 km 2) with differences in their pre-3600 Ma histories, and they are tectonically separated from each other by younger...[Show more]
