摘　　要：Objective Geological records of Earth history in the Hadean(>4.0 Ga)are critical for understanding the earliest evolution of the planet’s continental crust.Unfortunately,investigation of such proto-continental crust,including its formation mechanism and evolution,has been extremely limited due to the scarcity of Hadean terranes,because most ancient crustal records have been destroyed during subsequent geological processes.
