围绕对地质时间的认识,地层学取得了从岩石地层学、生物地层学和旋回地层学3次里程碑性的重大进展.以生物地层学为基础并与放射性同位素定年技术相结合建立的、以百万年为计时单位的地质年代表既创造了地层学的辉煌,也在一定程度上降低了地质学对精确数字定年的不懈追求和为人类社会服务的功能.本文以时间为线索,简要回顾了地层学解读时间的漫长过程,阐述了旋回地层学概念的起源、形成和发展,以及旋回地层学与层序地层学在科学目标、研究内容和研究方法上的异同.以广西晚泥盆世弗拉期-法门期之交海相碳酸盐地层为例,从理论与实践的结合上剖析了旋回地层学的研究方法以及在岩石地层学和生物地层学基础上构建高分辨率,并能与人类社会时间接轨的地质时间坐标的广阔前景和科学意义.
Surrounding the understanding of geologic time, stratigraphy has made three major milestones from lithostratigraphy, bio-stratigraphy and gyrato-stratigraphy, and based on bio-stratigraphy and dating with radioisotope dating, Geochronology of thousands of years as the unit of chronology not only created the gloriousness of stratigraphy, but also reduced the relentless pursuit of precise numerical dating of geology to a certain extent and the function of serving human society.This paper takes the time as a clue and briefly reviews Stratigraphic interpretation of the long process of elaboration of the origin, formation and development of the concept of cycle stratigraphy, as well as the similarities and differences of the scientific objectives, research contents and research methods of the cycle stratigraphy and stratigraphy.With the late Devonian Taking the marine carbonate formations at the Talamen-Famenian period as an example, this paper analyzes the research methods of cyclone stratigraphy from the combination of theory and practice, as well as the construction of high resolution based on lithostratigraphy and biostratigraphy, The Broad Prospects and Scientific Significance of Geological Time Coordinates in Conjunction with Human Society.
