环状的太平洋暗示着它与地球上别的狭窄的扩张分裂型大洋有不同的成因和演化历史。事实上,从环太平洋构造域和环太平洋地体研究以及对太平洋板块复原再造的结果确实印证了这样一种设想。从洋底分布的玄武岩年龄上限和滨太平洋地区的构造热历史研究表明了这一灾难性事件发生在二叠纪与三叠纪之间。这一撞击事件形成了具有明显微量元素异常的二叠纪—三叠纪界线粘土层,并与地史上最大的一次生物绝灭(约96%以上生物种灭亡)以及地磁场的重大倒转,古气温和大气成份的突然性变化,地球的剧烈性膨胀,海水的大规模损失,地球自转速度加快等一系列实发性事体相重合。
The ring-shaped Pacific suggests that it has a different genesis and evolutionary history than any other narrowly divergent ocean of oceans on Earth. In fact, the results from the study of the Pacific Rim and the Pacific Rim and the restoration and rebuilding of the Pacific plate really confirm such an assumption. The basaltic upper age distribution from the ocean floor and the tectono-thermal history of the coast of the Pacific Ocean show that this catastrophic event occurred between the Permian and Triassic. This collision resulted in the formation of the Permian-Triassic boundary clay layer with obvious trace element anomalies. Compared with the largest biological extinction in the history of the earth (the death of more than 96% of all species) and the significant reversal of the geomagnetic field, Sudden changes in temperature and atmospheric composition, drastic expansion of the Earth, large-scale loss of seawater, and acceleration of the earth’s rotation coincide with a series of real events.
