AB - Greenland hosts some of the most significant alkaline igneous complexes in the North Atlantic region, representing key archives of mantle processes, crustal evolution, hydrothermal alteration, and glacial–climatic interactions. These complexes, including Kangerdlugssuaq, Ilímaussaq, Grønnedal-Íka, and Qassiarsuk, provide valuable insights into magmatic differentiation, isotopic evolution, mineralization, and water–rock interactions. In addition, glacial retreat studies and sedimentary investigations from East Greenland and beyond contribute to understanding post-magmatic surface processes and paleoclimatic transitions. This review synthesizes petrological, mineralogical, geochemical, isotopic, and cryospheric research to evaluate the evolution of Greenland’s alkaline systems and their broader geodynamic and environmental implications. Emphasis is placed on magma genesis, fractional crystallization, carbonatite association, ikaite formation, aerosol iron transport, and ice-sheet retreat history. The integration of magmatic and surface-process studies provides a comprehensive framework for understanding lithosphere–hydrosphere–cryosphere interactions in high-latitude tectonic settings.
