摘　　要：本文简介了黄赤交角、偏心率、岁差等地球轨道三要素和米兰柯维奇理论。概述了第四纪及前第四纪沉积物中与地球轨道三要素有关的周期性沉积记录，指出对旋回沉积的研究。Three orbital elements of the Earth:precession,declination and eccentricity,and Milankovitch theory are introduced briefly.Also,periodic sedimentary records related to the three orbital elements in Quaternary and pre Quaternary sediments are described.It is pointed out that the study on the the periodic records may provide a marker for division and correlation of strata.

关 键 词：米兰柯维奇理论 沉积旋回 地层划分 第四纪
