Probable Cold and Alkaline Surface Environment of the Hadean Earth Caused by Impact Ejecta Weathering
Abstract Constraining the surface environment of the early Earth is essential for understanding the origin and evolution of life. The release of cations from silicate weathering depends on climatic temperature and pCO2, and such cations sequester CO2 into carbonate minerals in or on the seafloor, pr...
