摘要

•2527–2511Ma monzogranite–syenogranite in Eastern Hebei-Western Liaoning areas.•High REE magma stemmed from K-rich juvenile crustal materials at low pressure.•Low REE magma formed by fractionated crystallization of the high REE magma.•Neoarchean back-arc basin along the north of the Eastern Block, NCC.
