Precambrian Hongqiyingzi Complex at the northern margin of the North China Craton: Its zircon U-Pb-Hf systematics, geochemistry and constraints on crustal evolution
Precambrian Research(2019)
摘要
•Neoarchean calc-alkaline granitoid gneisses and late Paleoproterozoic granitoid intrusions.•LA-ICP-MS and SHRIMP zircon U-Th-Pb chronology and Lu-Hf systematics.•Neoarchean calc-alkaline magmas were derived partial melting of juvenile crustal materials.•Paleoproterozoic granitoid magmas came chiefly from partial melting of metamorphic basalts and greywackes.•Hongqiyingzi Complex is likely crucial signatures of the northernmost end of the TNCO.
