摘要: 海南岛北部沉积了巨厚的新生界,其更新统的松散沉积大致可划分为早更新世的湛江组,中更新世的北海组,晚更新世的八所组(俗称"老红砂").北海组系1934年邓植仪在广西北海地区考察土壤时对一组棕红色砂质壤土的命名.同时潘德顿(R.L.Pendleton)也将粤西沿海,包括雷州半岛和琼北的棕红色沙壤土称为北海系(Palchai series).

Abstract: According to the field observation and preliminary experiment.the authors discuss the origin of the Beihai Formatlon,the palaeogeographic variation of late Quaternary and the neotectonlc movement in northern Hainan Island.The Beihai Formation widely distributes in the region formed in middle pleistocene with a steady horizon,has the characteristics of both terrestrial and marine origins and consists of different landforms which show the obvious regional differences of the neotectonlc movement in northern Hainan Island since middle pleistocene.In a word the research.of the Beihai Formation development not only has academic significance but also benefits the studies of the Quartemary palaeogeography and neotectonic movement in northern Hainan Island.
