Palaeoproterozoic tectonic evolution of the Jiao–Liao–Ji Belt, North China Craton: Geochemical and isotopic evidence from ca. 2.17 Ga felsic tuff

The Palaeoproterozoic tectonic evolution of the Jiao–Liao–Ji Belt (JLJB) in the North China Craton remains controversial, particularly in the absence of adequate evidence for oceanic plate subduction. Here, we report SHRIMP U–Pb zircon ages, whole‐rock geochemistry, and Sm–Nd isotope data on felsic...
