The Chaotian is a proposed time division of the geologic time scale. First proposed in 2010 as an eon, it is named after Chaos, the primeval void in Greek mythology. This proposal defines the Chaotian eon as a solar system wide time between the initiation of planetary formation and the hypothesised collision of the Protoplanet Theia with the proto-Earth. As of 26 December 2020 neither proposal had been adopted or officially ratified by the International Union of Geological Sciences.

  • The Chaotian is a proposed time division of the geologic time scale. First proposed in 2010 as an eon, it is named after Chaos, the primeval void in Greek mythology. This proposal defines the Chaotian eon as a solar system wide time between the initiation of planetary formation and the hypothesised collision of the Protoplanet Theia with the proto-Earth. A revised proposal in 2012 suggested the Chaotian as the first era of the Hadean representing the time between the formation of the solar system c. 4.567 Ga and the oldest preserved crustal material on Earth, a c. 4.404 Ga detrital zircon from the Jack Hills of the Narryer Terrane in Western Australia. As of 26 December 2020 neither proposal had been adopted or officially ratified by the International Union of Geological Sciences. (en)

Estes são o zircão, o mineral mais antigo no de na Austrália Ocidental encontrados e datados 4,404 ± 8 milhões de anos atrás De acordo com a primeira proposta, ela precede o éon Hadeano e é a mais antiga eternidade na história do planeta Terra. O fim do Caotiano foi marcado pela hipotética hipótese da proto-Terra e um corpo do tamanho de um planeta chamado Theia, levando à formação da Lua. Alternativamente, é definida como a primeira era do éon Hadeano, antes da formação da primeira crosta na Terra. A partir de 2012, é considerado parte de uma revisão proposta da escala de tempo Pré-Cambriano. (pt)
