摘要
阐述了辽东半岛沿海第四纪沉积地层的特征与分布,该区第四纪地层不发育和发育的不平衡。地层厚度较薄,一般为20～50m,最大厚度70m左右,其变化趋势大体上呈从低山丘陵前到沿海地区逐渐变厚。早更新世地层分布很零散,晚更新世和全新世地层分布也较局限。该区缺少典型地层剖面,地层结构较简单,垂向相序明显。该区沉积物的成因类型较多,成因也较复杂,明显受控于地貌形态因素。
The characteristics and distribution of Quaternary Strata along the coast in Liaodong Peninsula are described in this paper. The stratigraphy of Quaternary in the area has not been developed well,the distribution not so wide. The strata is comparatively thin, about 20-50 m in thickness. The dispersive distribution of strata of early and middle Pleistocene and the limited distribution of the strata of late Pleistocene and Holocene are presented. There are more than 10 kinds of sediment types of Quaternary in this area, among which slope diluvium, alluvial diluvium and alluvium are well developed and have thick deposition.
