珠江口盆地珠Ⅰ、珠Ⅲ坳陷裂陷期湖相分布差异及其控制因素
Different distribution of lacustrine facies and its controlling factors during rifting stage, ZhuⅠand ZhuⅢDepressions, Pearl River Mouth Basin
摘要
Abstract
The distribution of lacustrine facies during rifting stage in the Zhu Ⅰ and Zhu Ⅲ Depressions of the Pearl River Mouth Basin shows that lacustrine facies spread much more widely in the Zhu Ⅰ Depression. It might be explained by the smaller extensional level of the Zhu ⅢDepression. The extensional level of a depre-ssion is affected by many factors, such as stress orientation, basement lithology and region faults. The differences of basement lithology, sag distribution, large potential fault below Cenozoic and sag-controlling fault orientation lead to the different extensional level of the ZhuⅠand ZhuⅢDepressions, and further control the different dis-tribution of lacustrine facies.关键词
