摘要: 海南岛沿海的第四系主要分布于滨岸带的滨海平原、三角洲平原和北部火山岩台地地区。其沉积厚度深受构造的控制。三个断隆区(图1)的第四纪沉积浅薄,一般厚5.6—13.0米,缺失下更新统。三个断陷区,都沉积了较厚的第四系。琼北断陷区,除火山岩外,第四系的沉积厚度多为20—30米,最厚达79多米(儋县蚂蝗岭);琼南断陷区,第四系厚度约30米。最厚58.7米(乐东九所东山脚);琼西断陷区的第四系厚度约20米。第四系厚度均由沿海向内陆变薄。

Abstract: This paper deals with the Quaternary stratigraphy of Hainan Island by means of the C14 dating, K-Ar age method, thermoluminescent method, paleomagnetic method, stratigraphic correlation, sedimentary facies and sedimentary cycles, as well as climatic periods reflected by spore-pollen analysis.
