层序地层学的研究状况及有关理论问题探讨

简要回顾了层序地层学的起源和发展历史．将层序地层学的发展划分为起源阶段、经典层序地层学阶段和高分辨率层序地层学阶段；在总结了层序地层学取得的主要成就和存在的问题以及难点的基础上，展望了层序地层学的未来和前景。最后．对有关层序地层学研究等理论问题作了初步的探讨，提出以初始海泛面作为层序的界线更为合理和实用，且优越于经典层序边界，并从理论上进行了论述；讨论了层序地层学理论在优化年代地层界线层型的作用，认为在海相地层中，层序的初始海泛面应该是选择全球界线层型剖面点的一个重要参考标准；在陆相地层中，作者提出．界线层型剖面点建立在最大洪泛面上是最好的选择，即应将陆相地层的界线层型剖面点建立在最大海泛面上第一个广泛分布的化石带之底。

Current Situation of Sequence Stratigraphy and Discussion on Related Theoretic Problems

The sequence stratigraphic origin and the development history are briefly reviewed, the development of sequence stratigraphy is divided into the origin stage, the classical sequence stratigraphy stage and the high resolution sequence stratigraphy stage. On the basis of summarizing the main achievement and the existing problems, the sequence stratigraphy is obtained, the future and prospects of sequence stratigraphy are forecasted . finally, a preliminary discussion on theoretic problems and related sequence stratigraphy research are made. It is suggested the first marine-flooding surface is the sequence boundary, and the boundary is more reasonable and practical, also superiorly than the classical sequence-boundary, and it is theoretically elaborated; the function of sequence stratigraphic theory on reasonable chronostratigraphic boundary stratotype is discussed, and the first marine-flooding surface is an important reference standard in choosing the global boundary stratotype in the marine facies stratum; it is proposed that maximum flooding surface is the best choice of boundary stratotype in continental facies stratum, namely boundary stratotype point should be established on the bottom of widespread distributed fossil zone above the maximum flooding surface.
