Calc-alkaline rocks of the 2.74 Ga Marshall assemblage have small massive sulfide deposits.

Parts of these assemblages contain widespread hydrothermal alteration and host small massive sulfide deposits.

The Abitibi belt also has some of the largest massive sulfide deposits in the province.

An unusual feature of this sulfide deposit is the large degree of magnetite at the actual showing.

About 60% is in laterites and 40% is in sulfide deposits.

Alteration not associated with the ore forming process may also be omnipresent both above and below the massive sulfide deposit.

These locations have shown promising amounts of gold in the area's sulfide deposits (an average of 26 parts per million).

Sperrylite has been identified in Finland from sulfide deposits generally associated with layered mafic-ultramafic complexes.

Oxidation of sulfide deposits occur during the geological process called weatherization.

Assuming the depth matches the known surface area, this deposit would be among the world's largest sulfide deposits.
