| 摘 要： | 古气候是影响陆相层序发育的一个重要因素，其周期性变化是源于天文旋回的驱动力（即米兰柯维奇假说）。米兰柯维奇天文旋回包括偏心率旋回、倾斜率旋回和岁差旋回，这几个轨道参数所驱动的古气候变迁，分别形成了周期为１０万年（或４０万年）、４万年及２万年的高频层序，即小层序组、小层序及小层单元，研究结果表明，泌阳断陷湖盆的高频层序是由地球轨道旋回所驱动的古气候周期性变迁所形成的。

| Abstract: | Palaeoclimatical cyclic transformation which is an important factor to control the development of terrigenous sequence was caused by the orbit cycle(namely, Milankovitch hypothesis). Milankovitch orbit cycle consists of eccentricity, inclination and procession of equinoxes, which lead to palaeoclimatical cyclic transformation and form high frequency sequence, parasequence and beds with cyclic time of ten(or forty), four and two thousand years respectively. High frequency sequence of lacustrine basin in Biyang fault depression was formed by palaeoclimatical cycle transformation which is caused by Milankovitch orbit cycle. |
