Why Greenland's Natural Resources Are So Desired: A Geologist's Perspective
Greenland, the largest island on Earth, is a treasure trove of natural resources, according to a geologist. It boasts some of the richest stores of critical raw materials, valuable minerals, metals, and a vast amount of hydrocarbons, including oil and gas. These resources are essential for green technologies and the global energy transition.
One of the most fascinating aspects of Greenland's geology is its diverse history over the past 4 billion years. It contains some of the oldest rocks on Earth and truck-sized lumps of native iron. The discovery of diamond-bearing kimberlite "pipes" in the 1970s showcases the island's potential for valuable gems. Geologically, it's rare for an area to have experienced all three key processes that generate natural resources: mountain building, rifting, and volcanic activity.
The island's sedimentary basins, such as the Jameson Land Basin, hold significant potential for oil and gas reserves, similar to Norway's rich continental shelf. However, high costs have limited commercial exploration. Metals like lead, copper, iron, and zinc are also present in the onshore sedimentary basins and have been mined locally since 1780.
Greenland's volcanic history has contributed to the discovery of rare earth elements (REEs) like niobium, tantalum, and ytterbium in igneous rock layers. These REEs are crucial for wind power, electric motors, and high-temperature magnets. Greenland is predicted to hold sufficient sub-ice reserves of dysprosium and neodymium to meet over a quarter of the world's future demand, making them economically important yet difficult to source.
The global energy transition, driven by the dangers of burning fossil fuels, has major implications for Greenland's natural resources. As the ice melts, revealing potential mineral resources, a dilemma arises. Should Greenland's resource wealth be extracted to sustain the energy transition, despite the environmental consequences, including despoiling its landscape and rising sea levels? Greenland's government heavily regulates mining and resource extraction, but pressures to loosen controls may increase with the US's interest in the island's future.
