AbstractThe Grenville Province exposes the deep crustal root of a Himalayan-type collisional orogen. However, most of its components predate collisional orogeny, and the main episodes of crustal build-up are Andean in type. Many of the ensuing volcano-plutonic arc belts are now parts of the gneiss complexes that typify large segments of the Grenville Province. Ages of inferred magmatic arcs, intra-arc rifts, aborted back-arcs and island-arcs components range from Archean to Mesoproterozoic, most being Labradorian (1.71-1.60 Ga), Pinwarian (1.52-1.46 Ga), or Elzevirian (ca. 1.35-1.19 Ga). Sedimentary basins and intrusive suites, including those with anorthosite massifs, host base metal (Zn), Fe- and hemo-ilmenite (Fe-Ti), and Fe oxide Cu-Au-REE-U deposits, and could collectively host Carlin, sedimentary exhalative, magmatic Ni-Cu-Co sulphides, PGE, Fe-Ti-V-P, and rare metal deposits. Recognized volcano-plutonic belts host some volcanogenic massive sulphide deposits or share hallmarks of volcanogenic massive sulphide, Fe oxide Cu-Au-REE-U, epithermal Au, and porphyry Cu deposits. The main aim of this synthesis is to inform and, through that information, disparage the wasteland paradigm that has afflicted the Grenville Province for so long. Compared to the Superior Province, the Grenville Province is under-explored, under-prospected, and under-mapped but as it is, to a large extent, a reworked equivalent of the Andes, there is no reason why it should not be as prospective. Like the known deposits, undiscovered deposits are likely to be metamorphosed and perhaps to have undergone ore mineral beneficiation providing a means to further increase the attractiveness of the Grenville Province.
