The Mârmorilik Formation is one of the most important metasedimentary formations in the Precambriah of Greenland. lt is the host rock of the Sorte Engel (Black Angel) zinc-lead ore body, it is the largest potential source of calcitelimestone in West Greenland, and it is a striking marker horizon which greatly facilitates the recognition of major structures in tile Precambtian basement. The formation is composed almostentirely or carbonate rock (dolomite arid calcite marbles); and the original depositional thickness of these rocks has been estimated to be more than 1 km (Henderson & Pulvertaft, 1967) an order of thickness that one of us (A.A.G.) has confirmed during recent detailed mapping south-east of Mârmorilik.
