چکیده انگلیسی
To reconcile the 2.55 to 2.5Â Ga TTGs derived from overthickened crust, the 2.51 to 2.50Â Ga calc-alkaline volcanic rocks derived from thickened crust, tholeiitic basalts representing low pressure and an extensional tectonic setting, 2493Â Ma leucosyenogranites derived from overthickened crust, 2437Â Ma biotite-monzogranites derived from slightly thinner crust than leucosyenogranites but still thickened, as well as the clockwise hybrid ITD and IBC P-T paths of the HP granulites and widespread extension and rifting setting within the NCC from 2300Â Ma, we propose a model of an evolving subduction process. Among them, the composition of the 2.5Â Ga Changyukou volcanic rocks and potassic granites as well as the clockwise hybrid ITD and IBC P-T paths of the HP granulites may reveal that the tectonic setting in Northwest Hebei was in a transition stage from a subduction-related compressional regime to an extensional regime related to plate rollback.
