【摘要】：层序地层学后Exxon时代,层序模式的多样化代表了科学家们对复杂地层记录及其响应机制的深入认识,在赋予各种层序地层模式较强针对性的同时,也引起了许多概念体系的不协调。因此,以寻求概念术语一致性为目的的层序地层学标准化,就成为当今层序地层学所面临的一个重要科学命题。层序地层学的发展历程中,正常海退与强迫型海退的识别与区分为层序形成过程的系统描述奠定了重要基础,由于这些过程可以独立于层序地层模式,所以成为迈向标准化成功的第一步;河流相层序模式中非常规体系域概念的引入,即低和高可容纳空间体系域,同样因其独立于层序模式存在的特性,代表了层序地层学标准化又一次成功的尝试。鉴于地层堆积作用过程的旋回性和复杂性,以及地层记录的非渐变性和不完整性,追逐层序地层模式多样性所表征的变化性,以及蕴含着变化性的标准化本质,将为层序地层学的进一步发展提供更多的思考线索和途径。
[Abstract]:In the post-Exxon era of sequence stratigraphy, the diversity of sequence models represents scientists' in-depth understanding of complex stratigraphic records and their response mechanisms, and at the same time endows various sequence stratigraphic models with strong pertinence. It also leads to the incongruity of many conceptual systems. Therefore, the standardization of sequence stratigraphy, which aims to seek consistency of conceptual terms, has become an important scientific proposition facing sequence stratigraphy today. In the development of sequence stratigraphy, the recognition and differentiation of normal regression and forced regression laid an important foundation for the systematic description of sequence formation process, because these processes can be independent of sequence stratigraphic model. So it became the first step toward standardization; the introduction of the concept of the unconventional system tract of the fluvial sequence model, that is, the low and high accommodation space system tracts, is also due to its characteristics independent of the sequence model. It represents another successful attempt to standardize sequence stratigraphy. In view of the cyclicity and complexity of the process of stratigraphic accumulation, as well as the non-gradual variability and incompleteness of stratigraphic records, the pursuit of the variability represented by the diversity of sequence stratigraphic models, as well as the standardized nature of variability, It will provide more thinking clues and approaches for the further development of sequence stratigraphy.
