通过 10余年来对中朝板块旋回层序、事件及构造演化的调查研究和综合分析 ,笔者编制了中朝板块旋回层序、事件和形成演化综合图 ,深刻地认识到地质科学是复杂性的科学体系。复杂系统研究要求重组现有的科学划分 ,实现跨越岩石矿物学、古生物学、层序地层学、地质地球化学、磁性地层学、古地理学、古构造学、天文学、海洋学及矿床学等不同学科的协同 ,从而促进学科的交叉和融合 ,以求学科体系理论和方法论的深刻变革 ,以推动地质科学的发展。这就是笔者提出以宇地系统观来综合研究地球、层序、事件和演化的基本思路。依据宇地系统作用原理 ,研究了中朝板块从元古宙至中新生代的旋回层序、事件和演化历史。从 180 0Ma至第四纪共划分出 2 0个超旋回或巨旋回周期和百余个奥尔特周期 ;还研究了海泛事件、隆升间断事件、跷跷板运动事件、臼齿碳酸盐事件、热事件、反极性事件、岩溶事件、火山喷发事件、风暴事件、物源区类型及古构造演化等一系列重大事件。应用宇地系统周期等时原理对中朝板块拗拉谷、鲕滩台地建造、前陆盆地演化和陆相裂谷盆地 ,按长偏心率周期进行了古地理演化的精细研究 ,再现了中朝板块构造、古地理和地层格架的演变 ,并对具全球性意义的大气圈、水圈、生物圈。

Through ten years of research and synthesis analysis on the cyclic sequence, events and tectonic evolution of the Sino Korea plate, the authors compiled a comprehensive chart that shows the cyclic sequence, events and the formational evolution of the Sino Korea plate, and understood profoundly from the research that the geoscience is a complex scientific system. The research on the complex system requires that the researchers recompose the existing scientific divisions, and realize the cooperation between many subjects of the geoscience, e.g., the litho mineralogy, paleontology, sequence stratigraphy, geological geochemistry, magnetism stratigraphy, paleogeography, paleotectonics, astronomy, oceanography and so on, which will promote the intercross and inosculation of knowledge and the profound transformation of the theory and the methodology of the scientific system, so as to promote the development of the geoscience. This is the basic clue of the authors to present the Cosmos Earth system viewpoint to the synthesis study of the Earth, sequence, events and evolution. From the theory of Cosmos Earth System, the authors studied the cyclic sequence events and evolutionary history between Proterozoic and Mid Cenozoic in the Sino Korea Plate, and divided the evolutionary history this plate into 20 super cyclic or super mega cyclic periods and more than 100 Oort periods. The research stressed on series of important sea flooding events, uplift interruption events, tilting movement events, molar tooth carbonate events, thermal events, reversed polarity events, karst events, volcanic explosion events, storm events , types of resource area and its paleotectonic evolution. By means of isochronous theory of Cosmos Earth System periodicity, the authors elaborately studied (based on long excentricity and periodicity) the paleogeographic evolution of Aulacogen in Sino Korea Plate, oolitic beach platform formation, foreland basin and continental rift valley basin, reconstructed the evolution of tectonic paleogeography and stratigraphic framework. Finally, they made a deep exploration in global atmosphere, hydrosphere, biosphere, lithosphere, mineralization and other important Earth evolutionary events. Lots of facts suggest that the cyclic sequence and the multi surface such as sequence interface, system tracts, maximum flooding surface and periodical evolution of many important geological events in Sino Korea plate showed the development and interwork of multi sciences, which are the results of the evolution of the time structure in comprehensive systems. Global rhythm provides the evidence for the critical nature of the self organization. Just as what's pointed out in the generalized theory of relativity of Einstein, time and space are the two aspects of the united time space structure, which are combined together by means of the movement of the matters. A broad sense of the Cosmos Earth System connected by the multi composition matters of the Earth and the multi composition movements of the Cosmos will be a new research area of geoscience in the 21th century.
