2.33Ga～2.06Ga的δ13Ccarb正向漂移事件已被确认为一次全球性事件。与之相伴,地球表层系统的性质发生了一系列变革性变化,证实了2.3Ga环境突变事件的客观存在。关于事件的起因,科学家提出了“雪球”效应、超级地幔柱活动/超级大陆裂解效应、地外撞击事件等多种可能,但均需进一步确定。δ13Ccarb正向漂移现象很可能会在更多地区发现,2.3Ga前后多方面的截然变化将被揭示,更多示踪手段将被运用于研究2.3Ga事件。 The δ13Ccarb forward drift event of 2.33Ga ~ 2.06Ga has been confirmed as a global event. Along with this, a series of transformative changes have taken place in the nature of the earth’s surface system, confirming the objective existence of a mutation in the 2.3Ga environment. With regard to the causes of the incident, scientists have proposed many possible effects such as snowball effect, super-mantle plume activity, supercontinental pyrolysis effect and extra-continental impact events, all of which need to be further confirmed. The δ13Ccarb forward drift phenomenon is likely to be found in more areas. The dramatic changes in many aspects around 2.3Ga will be revealed. More tracers will be used to study the 2.3Ga events.
