Abstract
Archean greenstone belts and their possible inclusion of fragments of ophiolites is an important research subject, since it is correlated with the nature of early oceanic crust, and can yield information on the nature of early planetary lithospheres, the origin of TTG (tonalite-trondhjemite-granodiorite) continental crust, the formation of early cratons and continents, and is related to when plate tectonics started in the Earth’s evolutionary history. This article briefly reviews the North China craton’s Archean ophiolite argument and proposes further studies aimed at understanding the generation of greenstone belts and Archean ophiolites, and suggests some key scientific questions that remain to be answered.
