| Abstract | The Archean, which represents more than a third of Earth's history, contains some of the largest and richest ore deposits of the World. Numerous cratons of variable size and age have been mapped (Fig.
1) and others are still being discovered or delineated thanks to the widespread use of highly-precise U-Pb geochronology. One of the specific characteristics of Archean cratons is the coexistence and juxtaposition of different and major styles of
mineralization (Robert et al., 2005), most particularly magmatic (komatiite-hosted) Ni-Cu-(PGE) sulfide deposits, Cu-Zn-Au-Ag-Pb volcanogenic massive sulfide (VMS) deposits, and greenstone-hosted Au deposits of different styles and ages.
The
objective of this special issue is not to discuss the differences between Archean and younger metallogenic processes or secular changes as it has been done in great detail elsewhere (e.g., Kerrich et al., 2000; Groves et al., 2005a, b; Kerrich et
al., 2005; Goldfarb et al., 2010; Huston et al., 2010; Naldrett et al., 2010); it is rather to contribute to a better understanding of some of the metallogenic and associated processes that were active at the Archean and that have implications on
genetic and exploration models. |
