Discussion about Base-level Changes in the Analysis of High-resolution Sequence Stratigraphy
-
摘要: 基准面有三个不同的概念,即侵蚀基准面、沉积基准面和地层基准面。目前对于基准面的解释和应用存在争论,在应用中尤其比较模糊。在对高分辨率层序地层学中地层基准面的解释进行分析及基础上,对其在解释以海相沉积环境为主的部分提出了质疑并就可容空间与地层基准面的关系问题进行了讨论。可容空间是层序地层学关键概念,基准面也是层序地层学很重要的概念,两者对于解释层序形成机制是非常重要的。侵蚀基准面、沉积基准面、地层基准面都是势能面,都是动力学界面,都是变化的,只是分析的基准不同、形成的机制不同。为了深入地揭示这三种基准面的特征,还应该考虑基准面的定量研究问题。Abstract: There are three different concep tions about base-level that are base level of erosion, base level of deposition and stratigraphic datum, respectively. At present, the arguments still exist in the explanation and the app lication of base-level, especially bas-level seems amphibious in use. The exp lanation of the stratification base-level in the high-resolution sequence stratigraphy is analyzed in this paper, and, in particular, the portion focused on illustration about marine facies sedimentary environment is questioned. The author discussed the relation between accommodation space and stratigraphic datum. Accommodation space is the key conception in sequence stratigraphy and base-level is also important, so they are very significant to illustrate the mechanism of the formation of sequence. Base level of erosion, base level of deposition and stratigraphic datum are all potential energy levels, kinetic surfaces and are all variable, just differing from the criterion of analyses and the mechanism of formation. To illustrate the features of these three base-levels profoundly, more questions of quantitative research into base-level should be considered.
