Cyclic Sequences, Events and Evolution of the Sino‐Korean Plate, with a Discussion on the Evolution of Molar‐tooth Carbonates, Phosphorites and Source Rocks

Abstract

Abstract This paper gives an account of the research that the authors conducted on the cyclic sequences, events and evolutionary history from Proterozoic to Meso‐Cenozoic in the Sino‐Korean plate based on the principle of the Cosmos‐Earth System. The authors divided this plate into 20 super‐cyclic or super‐mega‐cyclic periods and more than 100 Oort periods. The research focused on important sea flooding events, uplift interruption events, tilting movement events, molar‐tooth carbonate events, thermal events, polarity reversal events, karst events, volcanic explosion events and storm events, as well as types of resource areas and paleotectonic evolution. By means of the isochronous theory of the Cosmos‐Earth System periodicity and based on long‐excentricity and periodicity, the authors elaborately studied the paleogeographic evolution of the aulacogen of the Sino‐Korean plate, the oolitic beach platform formation, the development of foreland basin and continental rift valley basin, and reconstructed the evolution of tectonic paleogeography and stratigraphic framework in the Sino‐Korean plate in terms of evolutionary maps. Finally, the authors gave a profound discussion on the formation and development of molar‐tooth carbonates, phosphorites and source rocks.
