Geochronology and geochemistry of Liaohe Group and Liaoji granitoid in the Jiao-Liao-Ji Belt, North China Craton: Implications for petrogenesis and tectonic evolution

Zircon U-Pb geochronological, whole-rock geochemical, and Hf isotopic studies were carried out on Liaohe Group and Liaoji granitoid within the central part of the Liaodong peninsula, NE China, to understand the Paleoproterozoic evolutionary history of Jiao-Liao-Ji Belt, North China Craton. Zircon U-Pb dating indicates the studied metavolcanic rocks from Dashiqiao Formation in South Liaohe Group had protolith ages of 2170 ± 29 Ma, 2170 ± 11 Ma,...
