| 中文摘要:层序地层学为沉积盆地分析的一个重要手段和方法。层序地层学在沉积盆地分析中的参数包括宏观参数和微观参数。宏观参数特指沉积盆地中同一成因类型或成因相关的层序构成的层序组合体的总体特征，主要包括物质组成、宏观轮廓及叠置序列等。微观参数系指单个层序本身的识别标志，分为层序内部标志和层序界面标志。前者包括层序的几何形态、规模级别、内部构型、成因格架和充填序列等；后者包括界面的物理标识、剖面特征、成因属性和级别类型等。不同的层序参数类型揭示不同的成因背景，反映不同的动态过程和成因动力学意义。通过这些参数类型及其成因意义的研究，可分析层序形成与沉积盆地及板块构造的关系，进而研究层序的形成背景和成因动力学，最终为盆地动力学研究提供基础。 |

| Abstract:As an important method, the parameter of sequence stratigraphy applied to the sedimentary basin includes macroscopic one and microcosmic one. The macroscopic parameter, as the general characteristics of sequence genetic assemblage combined with genesis-related sequence or sequence sets, includes component,figure,and superimposition succession. The microscopic parameter, as the indicator of a certain single sequence, includes sequence one and sequence boundary one. The former includes geometry, hierarchy, architecture, framework, and filling succession, whereas the latter includes boundary indicator, characteristics, nature, and type. Different parameters reveal different genetic backgrounds and reflect different dynamic processes and genetic implications. By means of the parameter and the significance of sequence genetic dynamics, the relationship of sequence stratigraphy to sedimentary basin and plate tectonics can be analyzed, and the genetic background and dynamics can be discussed. All this provides the basic data for the sedimentary basin dynamics. |
