Early Precambrian rocks are widely distributed in the khondalite series belt of the North China Craton (NCC), and previous studies have shown that the metamorphic ages of ~2.5 Ga and ~1.95 Ga are widespread. The Neoarchean charnockite of the Yinshan Block has been a topic of great interest for understanding the Precambrian geology of the NCC. Although there is a broad consensus that there were two stages of the Late Neoarchean and Late Paleoproterozoic tectonic events in the northern margin of the NCC, there are still few reports of Archean research in the Jining area and ongoing controversy about whether the Jining area was involved in Archean tectonic events. SHRIMP zircon U-Pb dating of newly discovered charnockite and retrogressive biotite-hornblende gneisses together represent direct evidence for the superimposed reformation of two stages of Late Neoarchean and Paleoproterozoic tectonic thermal events in this region.
