... and fractionation of tholeiitic to calc-alkaline basalt-andesite. Pretectonic, synvolcanic tholeiitic intrusions (e.g., Dundonald sill, Kamiskotia gabbroic complex: 2.72-2.70 Ga) show in situ fractionation trends, and locally, have mixed magma textures with contemporaneous calc-alkaline granitoids...

... temperatures of 850° to 940°C. During the time of metal deposition, shallow-level fractionation of a tholeiitic parent produced Fe-Ti basalt magmas, as recorded in the ferroan upper zone cumulates of Kamiskotia Gabbroic Complex. Mafic magmas cooled with fractionation, assisted by advective heat loss...
