Paleoproterozoic (ca. 1.87-1.69 Ga) arc-related tectonothermal events on northcentral Yeongnam Massif, South Korea and its tectonic implications: Insights from metamorphism, geochemistry and geochronology

•Arc metamorphism in the northcentral Yeongnam Massif at ca. 1.87–1.86 Ga.•Arc magmatism in the northcentral Yeongnam Massif at ca. 1.87–1.69 Ga.•The arc events are linked to that in the northeastern Yeongnam Massif.•The Yeongnam Massif does not correlate with the North China Craton.
