Two contrasting Neoarchean metavolcanic rock suites in eastern Hebei and their geodynamic implications for the northern North China Craton

•Late Neoarchean supracrustal rocks in eastern Hebei Province, northern NCC.•Metavolcanic rocks in mature continental arc and back-arc basin setting.•Deformational and metamorphic history of the K-rich granitoid belt.•Neoarchean active continental margin setting with a southeastward subduction polarity.•Multi-stage northwestward trench retreats and subsequent arc-continent collisions.
