摘要
依据山地侵蚀与平原堆积是一个地文期的两种不同表现形式,以山地侵蚀期与平原粗(包括底部的不整合面)、细(包括表层的风化壳或古土壤)粒物质堆积期相关的原则,对华北地区新生代地文期进行重新命名。晚白垩纪地文期是北台期侵蚀—卢沟桥、无极期堆积,早第三纪地文期是甸子梁期侵蚀—孔店、沙河街期堆积,晚第三纪地文期是唐县期侵蚀—馆陶、明化镇期堆积,早更新世地文期是汾河期侵蚀—固安期堆积,中更新世地文期是湟水期侵蚀—杨柳青期堆积,晚更新世地文期是清水期侵蚀—欧庄期堆积,早、中全新世地文期是板桥期侵蚀—杨家寺、高湾期堆积,晚全新世地文期是段曲期侵蚀—岐口期堆积。
Mountain land erosion and plain accumulation are two different representations of physiographic time.Based on the correlation among,coarsely granular material at the lower part of plain,fine granular material at the upper part of the plain and the surface weathered crust or paleosoil,this paper renamed the physiographic time of North China,which are as follows: the late Cretaceous Period physiographic time is presented as Beitai Period Erosion-Lugou bridgeand Wuji Period Accumulation;the early Tertiary Period physiographic time is presented as Dianziliang, Period Erosion-Kongdian and Shahe River Period Accumulation;the late Tertiary Period physiographic time is presented as Tang County Period Erosion-Guantao and Minghua Town Period Accumulation;the early Pleistocene Epoch physiographic time is presented as Fenhe River Period Erosion-Gu'an Period Accumulation;the middle Pleistocene Epoch physiographic time is presented as Huangshui Period Erosion-Yangliuqing Period Accumulation;the late Pleistocene Epoch physiographic time is presented as Qingshui Period Erosion-Ouzhuang Period Accumulation;the early and the middle Holocene physiographic time is presented as Banqiao Period Erosion-Yangjiasi and Gaowan Period Accumulation;the late Holocene physiographic time is presented as Duanqu Period Erosion-Qikou Period Accumulation.
