P–T–t evolution of the high-pressure mafic granulites from northern Hengshan, North China Craton: Insights from phase equilibria and geochronology

•HP granulites record prograde path before inferred peak stage 760–820 °C/∼15 kbar.•Decompression to Tmax stage 840–860 °C/6–8 kbar, followed by isobaric cooling.•Metamorphic ages 1.90–1.83 Ga of the granulites represent the post-orogenic cooling.
