Why is Greenland so rich in natural resources?

Island's mineral and resource wealth is result of mountain building, rifting and volcanic activity over 4bn years

As recent manoeuvres over Greenland have made plain, this mostly ice-covered island contains some of the greatest stores of natural resources in the world, with huge volumes of oil and gas, rich deposits of rare-earth elements and rocks bearing gems and gold. So why did all the planetary goodies end up here?

Writing in The Conversation, the geologist Dr Jonathan Paul from Royal Holloway, University of London, explains how this mineral and resource wealth is tied to the country's geological history over the past 4bn years. Greenland is a bit of a geological anomaly, with land that has been pummelled in three different ways: mountain building, rifting and volcanism.
