East Greenland #22 is a finely laminated buff yellow cherty carbonate mudstone (dolostone). This sample was taken from the unit that directly overlies the Storeelv formation glacial deposits. The sharpness of the contact between the Storeelv glacial succession and the overlying cap carbonate implies a rapid transition ...

The Sir James Pit was operated for the mining of siderite, an iron carbonate ore. The siderite ore was originally deposited on the seafloor ~2.75 Ga as the result of seafloor hydrothermal venting in the Archean oceans. The dark outcrop seen here at the lip of the pit is thought to represent the primary vent from whic...
