In this presentation, I would like to take you on a journey to Greenland and present some research on the Ilímaussaq and the Skaergaard magmatic systems. Both intrusive complexes have a long history of investigation, but there are still many unresolved questions. In particular, the magma chamber processes of these complexes play a crucial role in the formation of ore deposits and need to be understood to explore for new resources.
The alkaline/peralkaline intrusion at Ilímaussaq is famous for its wealth of (rare) minerals and hosts REE-Nb-Ta-Zr mineralisation. The formation of this extraordinary magmatic complex is still debated and includes different magmatic and metasomatic models related to extended crystal fractionation.
In contrast, the mafic Skaergaard intrusion hosts sulphide-poor, blind Pt-Pd mineralisation that formed likely due to sulphide liquid immiscibility. I will present how we study these systems to unravel the ore forming processes.
