| 摘 要： | 根据大量的区域地质、钻井岩心、野外露头等资料,以及年代地层和生物地层的研究成果,将三水盆地古近纪地层划分出一个盆地充填层序、两个构造层序和6个层序;在构造层序地层研究基础上,以层序为编图单元,采用压缩法和瞬时作图法,编制了三水盆地古近纪层序岩相古地理图,系统地阐述了层序岩相古地理特征;通过古近纪不同时期的层序岩相古地理演化,将沉积充填分为湖泊细碎屑加积和顶部粗碎屑填积两个演化阶段。

| Abstract: | The tectonic sequences are examined for the Sanshui Basin, Guangdong on the basis of regional geological,well logs,field outcrops,chronostratigraphic and biostratigraphic data.One basin-filling sequence,two tectonic sequences and six sequences have been distinguished and six sheets of sedimentary facies and palaeogeographic maps have been constructed for the Palaeogene strata in the basin.The deposition and filling of the Sanshui Basin spanned two stages: lacustrine fine clastic aggradation in the early stage and coarse clastic filling at the uppermost part in the late stage. |
