Integrated seismic interpretation of the Larder Lake area, Southern Abitibi greenstone belt, Ontario, Canada
The southern Abitibi greenstone belt is characterized by a series of complex metavolcanic and metasedimentary rocks intruded by granitic plutons and batholiths, which makes the area a hardrock environment. In the Larder Lake area, these stratigraphic units are truncated by two major breaks, the …

Geochemistry and petrogenesis of unaltered and altered volcanic sequences in the southern Abitibi greenstone belt
The Abitibi greenstone belt is a volcanic-plutonic dominated subprovince of the Archean Superior structural province. In the southern volcanic zone (SVZ) of the Abitibi greenstone belt, there are numerous, well preserved, komatiite-tholeiite sequences in fault-bounded tectonostratigraphic terranes, …

Significance of magma mingling and mixing during the formation of the host-rock successions of Archean massive sulfide deposits in the Noranda camp, Abitibi subprovince, Quebec, The
… massive sulfide deposits of the Neoarchean Abitibi subprovince of northern Ontario and Quebec. With a historic production of 54.3 Mt of ore grading 2.2% Cu and 6.1 g/t Au, the Horne deposit was the largest base and precious metal producer within the district. The Quemont deposit, located …

Paleomagnetic Constraints on Assembly of the Superior Craton: Results from the 2.72-2.69 Ga Vermilion District of the Wawa Subprovince, MN
… plate motion during the accretion of the Wawa-Abitibi Terrane onto the Superior Craton, suggesting that subduction leading to ribbon continent accretion occurred at a higher velocity than observed in Phanerozoic time. However, more data is required before this motion can be fully confirmed.
