Arc-generated metavolcanic rocks in the Anshan–Benxi greenstone belt, North China Craton: Constraints from geochemistry and zircon U–Pb–Hf isotopic systematics

摘要

Graphical abstractDisplay OmittedHighlights?Volcanics erupted at 2574–2527Ma in Anshan–Benxi greenstone belt of the NCC.?The volcanic rock groups were derived from the dominant mantle wedge magmatism.?By the late Archean, Eastern Liaoning was a convergent plate margin environment.AbstractThe Anshan–Benxi granite-greenstone belt (ABGB) in the Eastern Block of the North China Craton mainly comprises supracrustal rocks of amphibole plagioclase gneisses, plagioclase amphibolites, chlorite schists, biotite schists, quartzites and banded iron formations (BIFs), and intrusive monzogranitic to syenogranitic gneisses. Based on geology, spatial distributions, lithologies and zircon U-Pb geochronology, the metavolca
