The mineral potential of the Palaeogene intrusions, East Greenland

More than sixty intrusions are catalogued in the Palaeogene East Greenland volcanic rifted margin. The plutonic suites range from ultramafic to felsic, from depleted basaltic to highly alkaline, and from upper crustal intrusions to subvolcanic centres and breccia pipes with related epithermal vein systems. The East Greenland magmatism lasted from 61 to 13 Ma. The Skaergaard PGE and gold deposit and the Malmbjerg molybdenum deposit have the potentials to become world-class size deposits.
