The Archean eon is a highly mineralized eon in geological time, producing a significant proportion of the world’s Au, Cu, Zn, and Ni. However, much of this mineralization is concentrated within the period from 2740 to 2620 Ma, a time characterized by extensive crustal growth and mineralization and referred to by Barley et al. (1998) as the "Late Archean bonanza." Numerous papers have been written about Late Archean mineral deposits and their tectonic environments, yet this Late Archean bonanza comprises only 120 m.y. of an eon that spanned from 4000 to 2500 Ma. By comparison, the period prior to the...
