The common occurrence of shear zones may be explained by the greater density
of the 'greenstones' relative to the surrounding gneisses, which permitted the
supracrustal assemblage to collapse through the hot, weak, Archean basement.

Definition. The Isua supracrustal belt is the largest contiguous complex of
Eoarchean supracrust (rocks formed at or near the Earth's surface) known on
Earth. It is located ca 150 km NE of Greenland's capital Nuuk, in West Greenland.
