The Tasiilaq region in SE Greenland records the suturing of two major cratons during the 1.9 Ga Nagssugtoqidian orogeny, with the Rae Craton to the north subducting beneath the North Atlantic Craton (NAC) to the south. Supracrustal rocks that were deposited prior to the orogeny, and record it, can b...
