Subaerial weathering played a key role in stabilizing Earth's continents. The emergence of continental landmasses above sea level triggered weathering processes that led to intracrustal melting and the formation of peraluminous granitoid magmas. This process reorganized the compositional structure of the continental crust during the Neoarchaean period. Weathering concentrated heat-producing elements (U, Th, K) into sediments, which were then incorporated into the deep crust. This enriched the crust and drove melting and chemical stratification, stabilizing the craton lithosphere. The chain of causality between weathering and crustal differentiation implies that craton stabilization was an inevitable consequence of continental emergence. Cratons, the most enduring blocks of continental crust, formed about 50% of Earth's continental crust and are some of the longest-lived geological features. They host critical mineral deposits and preserve ancient planetary environments. The stabilization of cratons in the Neoarchaean period is linked to the formation of granitoid rocks with elevated concentrations of U, Th, and K, which resulted from intracrustal melting and the incorporation of heat-producing elements into the deep crust. The formation of Neoarchaean granites, which are potassic and peraluminous, represents the final stage of crustal differentiation. These granites are enriched in HPEs, which significantly reduced temperatures in the deep crust and strengthened the lithosphere. The timing of this differentiation event, occurring between 3.1 and 2.5 Ga, marks the final stage of cratonization. The process was driven by the accumulation of sedimentary rocks enriched in HPEs, which, when incorporated into the deep crust, provided the necessary heat for melting and differentiation. The study shows that the heat production rates of Archaean TTG terranes were significantly lower than modern crustal compositions, indicating that crustal thickening alone could not explain the widespread melting and differentiation observed in the Neoarchaean period. Instead, the incorporation of sedimentary rocks into the deep crust, which were enriched in HPEs, provided the necessary heat for melting and differentiation. This process was supported by the presence of metasedimentary rocks in granulite terranes, which indicate significant melting and differentiation. The study also highlights the importance of subaerial weathering in the geological evolution of Archaean cratons. The weathering of TTG crust concentrated HPEs into sedimentary rocks, which, when buried, provided the heat required for internal differentiation of the continental crust and the formation of cratons. The timing of sedimentation, metamorphism, and magmatism in the Neoarchaean period is consistent with the formation of cratons, as evidenced by the presence of granulite-facies metamorphic rocks and granitoid plutons.
