摘　　要：The formation of felsic continental crust has been essential for the development of Earth as a habitable planet.The recycling of supracrustal materials,especially surficial water,has had a profound impact on the chemical compositions and physical properties of rocks and has therefore been critical for the formation and reworking of the crust.Although some studies have proposed that the recycling of supracrustal materials can be traced back to early Earth[1],the timing of initiation of this recycling is unclear.
