陆相地层的层序地层学:层序的特征与模式

陆相地层的层序地层学研究近年来取得了较大的进展，尤其在层序的组成、层序界线和最大洪泛面的识别以及层序模式的建立等方面研究得比较深入。层序地层的组成包括层序组合和层序的内部单元。层序界线和最大洪泛面的识别是陆相地层层序地层学研究的关键。目前已初步建立了箕状断陷盆地、坳陷盆地以及冲积地层背景的层序模式。

SEQUENCE STRATIGRAPHY OF CONTINENTAL STRATA: CHARACTERISTICS AND MODELS

The last few years has seen a considerable advance in sequence stratigraphy of continental strata, especially in the studies of sequence stratigraphic units, recognition of sequence boundaries and maximum flooding surfaces,and sequence models.The sequence stratigraphic units include the associations and internal units of the sequences. The recognition of sequence boundaries and maximum flooding surfaces is the key problem in the study of sequence stratigraphy of continental strata. The sequence models for a half graben-like fault basin, downwarped basin and alluvial strata have also been constructed in this paper.
