VMS- and Rift-Related Mafic Rocks• In mafic dominated settings (Mafic, Pelitic-Mafic, Bimodal-mafic):– Boninites and depleted island arc tholeiites (IAT)– MORB and back-arc basin basalts (BABB)• In felsic and sediment-dominant (Bimodal-felsic, Silclastic-felsic)– settings important to find alkalic and MORB.• Transitions from arc to non-arc signature mafic and felsic rocks areevidence <strong>for</strong> rifting and most VMS deposits occur within suchtransitionsArc to rift transitions in stratigraphy!
