The Archaean: Geological and Geochemical Windows into the Early Earth
Determinations of the age of the Earth as 4.54 ± 0.05 billion years (Ga) leave large part of its earliest history unknown. Isotopic and geochemical signatures in rocks as old as ~4.0 Ga indicate an evolutionary trend from mafic-ultramafic crust to tonalite-trondhjemite-granodiorite (TTG)-dominated m...
