中文摘要:

将不整合面理解为重要的时间屏障和地层界面,从而把不整合面及其可以对比的整合面所限定的地层单位定义为层序,并进一步将造成层序界面重复性的基准面变化归因于海平面变化,这种推测性的大胆解释,在层序地层学概念体系中就成为占主导地位的演绎性模式的重要基础,概念体系的建立和演变意味着工作方法和术语体系的更新和革命。在沉积地质学的宽广领域中,层序地层学还被誉为一个翻新了地层分析方法学最晚的一次概念革命。由于地层记录及其形成过程的复杂性,在层序地层学的发展历程中,曾经出现过明显的三个误判,即:(1)1977年的错误对比;(2)1988年的错误假设;(3)1999年的冗余修正。这三个误判,是前辈科学家们从复杂的地层记录及其形成过程中提取更多规律性的真实写照,从而具有鲜明的时代特色,并反映了层序地层学艰难的发展历程;追逐和总结这三个误判产生的历史背景及其所蕴含的科学意义,将更加有益于层序地层学的进一步发展。

英文摘要:

On the basis of an important concept that an unconformity can be understood as a time barrier and a stratigraphic boundary, the stratigraphic unit bounded by an unconformity and its correlative surface can be defined as a sequence; and further, the repeatability of sequence boundaries resulted from the base-level changes was attributed genetically to the sea-level change. This bold explanation with speculations became an important basis for the deduction model that is in the lead within the conceptual system of sequence stratigraphy. Both the establishment and the evolvement of the conceptual system represent the renovation and revolution of the work-method and term system. Thus, sequence stratigraphy has been praised as a latest conceptual revolution for the methodology of stratigraphic analysis in a broad realm of sedimentary geology. The complicacy of the stratigraphic records and their forming processes has resulted in three misreadings in the developing course of sequence stratigraphy, which can be summarized as follows: (1) a mistaken correlation in 1977~ (2) a mistaken assumption in 1988; (3) a redundancy amendment in 1999. These three misreadings are a true portrayal of senior scientists having strived to extract more regularities from sophisticated stratigraphic records and are endowed with the vivid peculiarities of times. It is very meaningful for the further advancement of sequence stratigraphy to pursuit and to summarize both the historical background resulting in these three misreadings and their scientific implications for sedimentology and stratigraphy.
