Figure 3. Generalized geologic map showing extent of early Archean (3770–3900 Ma) Itsaq Gneiss Complex in southern West Greenland (adapted from Nutman et al., 1984, 1996). Oldest sedimentary rocks and associated gneisses are along coast, represented by island of Akilia, and are intruded in places by Proterozoic Qorqut granites (Fig. 4).
