| 9. | The second terrace turned into a complex terrace because of the slackwater sediments caused by the yellow river ' s flood in late holocene
距今4000年左右的史前洪水阶地上加积了一层平流沉积物，形成复合型阶地，其下部为基座阶地，上部为上叠阶地。 |
| 10. | O curve of dsdp607 v30 - 97 show that loess began to deposit on the terrace of the yellow river about 1 . 20 ma b p , and passed thirteen climatic changes from drier and cooler to warmer and wetter later . the turn of sedimentation from alluvium to loess , an event of transformation from accumulation to down - cut of the yellow river , indicates a sharp tectonic uplift occurred around 1 . 2 ma b p . key words : loess - paleosol ; susceptibility ; climatic changes ; tectonic movement ; yellow river ; yangfan section
通过对杨范剖面黄土地层岩性特征沉积结构质量磁化率和频率磁化率的分析及与深海氧同位素曲线的对比，划分了剖面地层，初步确定了黄土沉积始于1 . 20 ma b p ,黄土沉积以来该区发生了13次大的干冷暖湿气候变化沉积转型指示河流强烈加积转变为河流侵蚀，代表约在1 . 20 ma b p发生过一次强烈的构造抬升事件。 |
