One hadean zircon from the Cambrian sandstone in the southern part of South China has a U-Pb age of 4107±29 Ma with ɛHf(t) value similar to that of the homochronous depleted mantle and Hf model age of 4102±21 Ma. This demonstrates the existence of hadean crustal remnant in South China. A close match between the U-Pb age and Hf model age with the highly position ɛHf(t) value indicates the growth...
