摘要: 老红砂是主要分布于我国东南沿海的,呈现以棕红色、红色、橙黄色为主的半胶结中-细砂质沉积物。笔者综述了前人在老红砂的分布与形态、沉积特征、形成机制、发育时代、红化作用、古地理环境等方面的研究成果,认为其为晚更新世沉积物,主体属风成沉积,热带-亚热带湿热季风气候导致的含铁物质分解和氧化是砂体红化的主要原因。根据研究现状,对存在的问题和今后的研究重点做一探讨和展望。

Abstract: Old red sand is a kind of semi-cemented and medium-fine sand sediment with the color of brown-red, red, or orange-yellow, and is mainly distributed along the southeastern coast of China. In this paper, the distribution, forms, sedimentary characteristics, formation mechanism, origin age, reddening process and paleoenvironment of old red sand are overviewed. Old red sand is a kind of aeolian sediment, it originated in the Late Pleistocene, and the reddening processes are mainly results from the decomposition and oxidation of iron-containing minerals due to hot and humid climate in tropical and sub-tropical areas. Because of the complexity of coastal geomorphology system, there are still some issues need to be deeply discussed.

Key words: old red sand, southeast coast of China, overview, prospect
