Greenland (Greenlandic: Kalaallit Nunaat) is the world’s largest island, covering approximately 2.17 million km², of which about 80% is ice-covered by the Greenland Ice Sheet. It lies between the Arctic Ocean and the North Atlantic, east of the Canadian Arctic and north-east of North America. Greenland is an autonomous territory within the Kingdom of Denmark, with extensive self-government. The capital and largest city is Nuuk. Despite its size, Greenland has a very small population concentrated along the ice-free coastal fringe.

Geographically, Greenland is dominated by the Greenland Ice Sheet, which reaches thicknesses of more than 3 km and profoundly influences global sea level and climate. Ice-free areas consist mainly of rugged mountainous coastal terrain, fjords, nunataks, and narrow lowlands. The highest elevations occur along the east coast and in the interior margins of the ice sheet. The climate is Arctic, with strong regional variation influenced by ocean currents and topography.

Geologically, Greenland is one of the most important regions on Earth for understanding Precambrian crustal evolution. Large parts of the island expose Archaean and Proterozoic crystalline basement, including some of the oldest rocks known on the planet, exceeding 3.8 billion years in age. These rocks form part of the North Atlantic Craton and include gneisses, greenstone belts, anorthosites, and granitoid complexes. Younger Proterozoic and Palaeozoic sedimentary sequences occur along parts of the coast, while Mesozoic and Cenozoic volcanic and sedimentary rocks are present in eastern and western Greenland, linked to the opening of the North Atlantic. The island’s geology records multiple episodes of continental assembly, rifting, and breakup.

Greenland possesses significant mineral and resource potential, much of which remains underexplored due to ice cover, remoteness, and harsh conditions. Known and prospective resources include rare earth elements (REEs), uranium, zinc, lead, gold, iron, nickel, copper, platinum-group elements, graphite, and gemstones. Several deposits are associated with alkaline intrusions, carbonatites, and mafic–ultramafic complexes, while others occur in greenstone belts and sedimentary basins. Offshore basins also have hydrocarbon potential, though exploration has been limited.

Greenland’s mineral resources and strategic Arctic location have attracted increasing international geopolitical attention. The United States has expressed strong interest in Greenland, citing its strategic importance and access to critical minerals essential for modern technologies and defence industries. This has included high-profile statements and proposals—particularly during the mid 2020s—suggesting the possibility of the United States acquiring Greenland, which were firmly rejected by both Greenlandic and Danish authorities. While not constituting a formal policy, such statements highlighted growing global competition over Arctic resources, shipping routes, and security as climate change reduces sea ice.

Historically, Greenland has been inhabited by Inuit cultures for thousands of years and was later colonised by Denmark. Since the late 20th century, Greenland has progressively expanded its self-governing powers, including authority over most natural resources, with the long-term option of independence remaining a political aspiration for some Greenlanders.

Administratively, Greenland is divided into municipalities under its autonomous government. Geologically and geopolitically, Greenland occupies a unique position: it is both a key archive of Earth’s earliest crustal history and an increasingly important focus of global strategic and mineral-resource interest, where geology, climate change, and international politics are becoming ever more closely intertwined.
