Boninites (LOTI), Depleted ArcTholeiites and VMS• Basaltic andesites with high MgO (>10%), Ni, Cr.• Very low HFSE and REE content• Depleted (U-shaped) normalized REE patterns.• Often associated with depleted tholeiitic• Require high temperatures to melt - indicative of highheat flow environment - necessary to drive hightemperatureVMS hydrothermal systems.• Examples: Kidd Creek, Snow Lake, Rambler-Ming,Fyre Lake
