The complexities of zircon crystllazition and overprinting during metamorphism and anatexis: An example from the late Archean TTG terrane of western Shandong Province, China

•A strong late Neoarchean (2.50–2.54Ga) tectono-thermal event was widespread in western Shandong Privonce.•The rocks undergoing this event include tonalite, trondhjemite, granodiorite, gabbro, quartz diorite, granite and paragneiss.•Belts A and B are different in ∼2.5Ga metamorphic and anatectic intensity.•This may indicate that the former was elevated to high crustal levels compared with the latter at the end of the Neoarchean.•In some areas of the NCC, 2.45–2.48Ga or younger metamorphic zircon ages may be due to superposition of the late Paleoproterozoic event.
