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 micro continental nuclei. To date signatures of the 3.95 – 3.85 Ga Late heavy Bombardment (LHB)…
