The Geological Map of Greenland at scale 1:2.500.000 provides a comprehensive regional synthesis of the geological evolution of Greenland from the earliest Archaean to the Quaternary. The map presents an integrated overview of Greenland’s geological framework, including extensive Precambrian crystalline basement provinces, major orogenic belts, Phanerozoic sedimentary basins and widespread volcanic provinces.

Greenland is characterised by large exposures of continental crust dominated by Archaean and early Proterozoic shield rocks that stabilised as part of the Laurentian shield. These basement provinces are complemented by younger geological elements developed mainly along the margins of the shield, where sedimentary basin formation, orogenic deformation and magmatic activity reflect successive tectonic regimes. The map illustrates the distribution and relationships of these geological units and highlights the structural and stratigraphic architecture of Greenland and adjacent offshore areas.

Late Proterozoic to Phanerozoic sedimentary basins, Palaeozoic orogenic belts, Mesozoic–Cenozoic rift systems and Tertiary volcanic provinces associated with the opening of the North Atlantic are all represented. Quaternary glaciation, which has profoundly shaped the present-day surface geology, is also reflected in the geological framework shown.

The map integrates onshore and offshore geological information compiled from field mapping, geophysical investigations and geological synthesis and provides a regional reference for geological interpretation, research, education and resource-related studies in Greenland.
