The Liaohe Group: An insight into the Paleoproterozoic tectonic evolution of the Jiao–Liao–Ji Belt, North China Craton

The Jiao–Liao–Ji Belt represents one of the largest exposed regions of Paleoproterozoic rocks along the eastern margin of the North China Craton. Paleoproterozoic basement material in this area is dominated by deformed and metamorphosed volcano-sedimentary successions with minor amounts of granitic and mafic intrusions. This study presents the results of a systematic zircon U–Pb geochronological, whole-rock geochemical and Sm–Nd isotopic...
