Zircon U–Pb–Hf isotopic and whole-rock geochemical studies of Paleoproterozoic metasedimentary rocks in the northern segment of the Jiao–Liao–Ji Belt, China: Implications for provenance and regional tectonic evolution

This study examines the original nature, tectonic setting, and evolution of Paleoproterozoic metasedimentary rocks of the North Liaohe and Laoling groups of the northern segment of the Jiao–Liao–Ji Belt, in the northeastern margin of the Eastern Block of the North China Craton, using new petrological, whole-rock geochemical, geochronological, and Lu–Hf isotope data. Zircons in the metasediments are magmatic and metamorphic in origin, yielding...
