摘要: One hadean zircon from the Cambrian sandstone in southern part of South China has a U-Pb age 4107±29 Ma with ɛ Hf(t) value similar to that homochronous depleted mantle and Hf model 4102±21 Ma. This demonstrates existence crustal remnant China. A close match between highly position indicates growth immediate reworking juvenile crust at ca 4.1 Ga. The prominent “Pan-African” Grenville zircons derived exotic sources were also found sample, which linking Gondwana period. complex histories tectonic evolution.
