Abstract:

Yanliao aulacogen is a typical sedimentary basin with global correlation implications of carbonate deposition. It is proposed the establishment of Wumishan Subsystem and series in this paper. And the Wumishan Supercycle of the Middle Proterozoic Jixian (MPSS Ⅱ) is a reef sedimentary supercycle with a huge sediment thickness formed by the balance compensation in the aulacogen basin evolution. Varieties of stromatolites well developed constitute a series of distinct sedimentary rhythms being indicative of a diverse of sedimentary environments, and suggest the rhythm of Milankovitch cycles, asteroid cloud cycles and the galactic plane cycles in the CosmicEarth System. Uplifting of the Shanhaiguan uplift resulted in the formation of a diverse order of sedimentary sequences of siliceous depositions derived from hot watersiliceous sediments and input of red source. Current study indicates that the Wumishan Supercycle be driven by the CosmicEarth System, which further improves our understanding of sedimentary responses to depositional rhythmic variations. Scientific exploration and practice has proved that only by establishing the concept of the universe of Earth Sciences, Earth Science research in order to continue to develop a new vision.
