摘要
根据近年来大量资料和信息及野外实地考察,笔者对第四纪冰期成因进行了讨论,文中引述大量资料表明:米兰柯维奇为冰期形成理论找到了确切的地质证据,天文因素与地壳变动及反馈作用的叠加是目前对第四纪冰期形成原因的最圆满的解释;并对大陆冰流次数与深海沉积所反应的冰期旋回的关系进行了探讨。
According to a lot of data obtained in recent years and on-the-spot observation,the development of research on the origin of the Quaternary ice age is described and discussed in this article. The anther believes that Milankovitch had found the precise geological evidecne for the theory of the formation of ice age. At presen, he astronomical factors, crustal movements and the superimposition of the feedback process provide the most perfect interpretation for the arrival of the clima e of ice age. The relationship between the frequency of continental ice flow and cycles of ice age indicated by the deposition of deep sea is also discussed in the article.
