采用岩石地层学、磁性地层学和地球化学等方法，结合 ＴＬ， ＥＳＲ，~(１４)Ｃ测年等，对广泛分布于闽南和粤西沿海的老红砂沉积地层及其形成时代进行了划分．研究表明，老红砂沉积从５５．４－９ｋａ ＢＰ都有发生，它们是晚更新世中、晚期末次冰期（玉木冰期）的风沙沉积．其中，大致可分成５６－４２和 ３０－１０ ｋａ两个相对较集中的老红砂沉积期，在这两期中，又以 ３０－１０ ｋａ晚玉木亚冰期（Ｑ_３~３）的老红砂发育规模最大，分布最广． By using methods of lithostratigraphy, magnetostratigraphy and geochemistry, combined with TL, ESR, ~ (14) C dating and so on, the sedimentary strata and their formation ages of the Old Hongsha widely distributed along the coast of Minnan and western Guangdong are divided . The study shows that the sediment of the Old red sand from 55.4-9ka BP occur, they are the late Pleistocene, the last Ice Age (Tamaki) deposition of sandstorms. Thereinto, it can be roughly divided into two relatively concentrated red mudstone ages of 56-42 and 30-10 ka. During these two phases, the old red sand was developed in the later 30- to 0-ka late Yushu sub-glacial period (Q 3 ~ 3) The largest and most widely distributed.
