【摘要】 在生物地层及年代地层研究的基础上,对本区上石炭统至中二叠统进行了层序地层学研究,从船山组至孤峰组下部共划分了5个三级层序、13个四级层序。通过五百多个米级旋回层序的研究,认为本区海盆有台地、台盆相间及盆地3个发展阶段,并得出4—6个米级旋回层序组成一个更高级别旋回的结论。更多还原

【Abstract】 Based on the biostratigraphic and chronostratigraphic data,the Carboniferous—Permian strata (from the Chuanshan Formation to the Gufeng Formation) in the Tonglu region of Zhejiang Province can be divided into five third-order sequences and 13 fourth-order sequences.In general,4—6 meter-scale parasequences make a sequence of higher order.Sequence stratigraphic data also indicate that the 500-m-thick Carboniferous-Permian succession in the Tonglu region represent a deepening upward sequence,beginning in platform facies and in deep water basinal facies.更多还原
