... are proposed that reflect the degree of involvement of magmatic and/or non-magmatic fluids and the nature of the mineralizing environment. A division into magmatic, non-magmatic, and hybrid magmatic–non-magmatic IOCG types is suggested. Typical magmatic end-member IOCG deposits include Lightning Creek...
