Abstract There are six distinct classes of gold deposits, each represented by metallogenic prov-
inces, having 100’s to ˚ 1 000 tonne gold production. The deposit classes are: (1) orogenic gold;
(2) Carlin and Carlin-like gold deposits; (3) epithermal gold-silver deposits; (4) copper-gold por-
phyry deposits; (5) iron-oxide copper-gold deposits; and (6) gold-rich volcanic hosted massive sul-
fide (VMS) to sedimentary exhalative (SEDEX) deposits. This classification is based on ore and
alteration mineral assemblages; ore and alteration metal budgets; ore fluid pressure(s) -
positions; crustal depth or depth ranges of formation; relationship to structures and/or magmatic
intrusions at a variety of scales; and relationship to the P-T-t evolution of the host terrane. These
classes reflect distinct geodynamic settings. Orogenic gold deposits are generated at mid-crustal
(4—16 km) levels proximal to terrane boundaries, in transpressional subduction--
plexes of Cordilleran style orogenic belts; other orogenic gold provinces form inboard by delamina-
tion of mantle lithosphere, or plume impingement. Carlin and Carlin-like gold deposits develop
