【摘要】 燕辽拗拉谷盆地是一个具有全球性对比意义的典型碳酸盐岩盆地。文中提出建立雾迷山亚系和相应统的划分方案,并指出蓟县系雾迷山亚系(MPSSⅡ)时期,属于盆地巨旋回的造礁沉积平衡补偿形成阶段,沉降幅度和沉积厚度巨大,发育有代表不同沉积环境的多种类型叠层石,在层序上构成明显的沉积韵律,并显示出受米兰科维奇周期、小行星云周期和银道面周期控制形成的不同级次的宇地系统沉积旋回韵律。同时,由于山海关古陆的周期性隆升作用,导致由热水硅质形成的燧石层和由红色物源输入形成的不同级次沉积层序,更为宇地系统控制层序的周期性增添了色彩。总之,蓟县系雾迷山期巨旋回是受宇地系统场控制成因的沉积响应的典范。科学探索与实践证明只有建立宇宙观的地球科学领域,才能不断地开拓地球科学研究的新视野。更多还原

【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.更多还原
