| 摘 要： | 从大连红黏土被第四系松散层所覆盖的现象出发，分析了大连地区沿海岸附近冰碛残丘的特征与形成过程。论证了大连地区陆地和海湾的红黏土都具有聚合沉积的特征，并且确定了大连红黏土形成期是在第四系冰川期之前。此外论证了大连红黏土是大连地区古地理古气候的标志性地层之一。

| Abstract: | The characteristic and the formation process of moraine hill in the Dalian area along the coast are analyzed from the phenomenon of the Quaternary incompact layer covering the Dalian red clay. The aggregation deposition, the characteristic about the terrestrial and thalassic red clay in the Dalian is demonstrated, and the formation age of the Dalian red clay is determined before the Quaternary glacial age. Furthermore, it is demonstrated that the Dalian red clay is one of the key layers of ancient geographical and climate in the Dalian area. |
