摘要
韩江三角洲ZK37孔第四系中的粘土矿物特征主要由沉积环境控制,它反映了该区的海陆变迁和气侯演化;这些特征与孢粉、微古、指相元素、^(14)C测年等研究结果表明该区晚第四纪存在三个明显的海侵期,而沉积环境变化与古气候有密切联系。
The clay mineral characteristics of the Quaternary sediments of the bore-hole ZK37 in Hanjiang Dalta,controled mainly by the variations of sedimeen-tary environments,reflect a series of interchanges of sea and land and limate of the worked area.The result of clay mineral study,associated with many other investigations such as fossil pollen,foraminiferas,element-indica-tors as well as radiocarbon dates,shows that the deltaic area had three stages of sea transgrassion during the Late Quaternary,The changes of sedimentary environment are relative to the climaic variations.
