Clockwise P–T–t paths were retrieved from the Mts. Huashan pelitic granulites. SIMS U–Pb dating of metamorphic zircons reveal the metamorphic ages of 1.85–18.2 Ga. The tectonothermal evolution of the TNCO started as early as ∼1.97 Ga and lasted as late as 1.80 Ga. An eastward subduction model for the TNCO is suggested in this study.
