| 摘 要： | 华北平原各省市第四系下限、内分层时限皆不相同，使相关研究缺乏统一的语言。依照《中国地层指南》的规定，据现有材料对华北平原第四系划分进行了再研究，明确河北平原原定早更新世固安组后于上新统，由于石油系统同样执行《中国地层指南》的原则，则固安组是明化镇组的同义名，应废弃。现有工作显示华北平原N／Q界线没有超过500m。 |
| 关 键 词： | 华北平原 第四系下限 固安组 明化镇组 地质时代 |

| Abstract: | The different time-scales had been used to determining the lower boundary of Quaternary system and in the subdivision of Quaternary in North China Plain, so there is no uniform language in relative research. According to the Guide of China Stratigraphy, the authors re-studied the subdivision of Quaternary system. Because the Gu'an Formation in the Hebei Plain determined Early Pleistocene formerly belongs to the stratum before 2.60Ma, this unit should to be placed in Upper Pliocene series. Owing to the principle of the Guide of China Stratigraphy also has been used by petroleum system, so the term of Gu'an formation is the synonym of Minghuazhen formation and the former should be abandoned. The boundary of Neogene/Quaternary system is located less than 500 m depth in the North China Plain. |
