新元古代曾发生过强烈的全球性冰川作用,本文回顾了新元古代晚期全球性冰川作用存在的证据及其特点,论述了新元古代冰期产生的原因,综述了一些代表性的“雪球地球”模型并探讨了“雪球地球”对早期生物演化的影响,最后对未来“雪球地球”研究趋势进行了展望.%A strong global glaciation took place on the Earth in Neoproterozoic. The evidences and characteristics of the glaciation during the Neoproterozoic is reviewed first while the mechanism of the glaciation is discussed. Then the models of the "Snowball Earth" and the effects of the glaciation on early life growth are summarized. Finally, the future development trend of "Snowball Earth" is forecasted.
