摘　　要：Objective The Hadean zircon and rock are critical to deepening our understanding of the developmental history of early Earth, making possible new avenues for the Pre-Archean Eon. However, the Hadean rock on Earth is only identified in Canada indeed. Comparatively, the Hadean zircon has attracted considerably more attention, as it is widespread and exhibits robust chemical and physical features that make it survive in extreme conditions, thereby providing a method of deciphering the evolution of the early Earth. It should be noted that most of the detrital or the xenocrystic zircons older than 4.0 Ga are found in Western Australia. Hadean zircon occurrences outside Western Australia have been also reported in Canada, west Greenland and China.
