论地壳运动的宇宙起因

摘    要:本文笔者认为,宇宙事件是地壳运动的主要动力之一。与地壳运动有关的宇宙事件共有12种,其中6种为正常事件,它们改变地球自转速率,并进而引起跃变地壳运动;另6种为灾变事件,它们直接启动岩石圈的板块运动,并导致突变地壳运动。地质历史上,可相应地划分出12个宇宙事件构造旋回,它们各自对应着不同型式和规模的宇宙事件和地质事件。质量较大的小天体对北冰洋、太平洋、大西洋和印度洋的4次冲击,塑造了全球地幔对流和海陆分布的基本格局。

关 键 词:宇宙事件  宇宙灾变  小天体冲击  冲击坑  板块构造  地壳运动  构造旋回

Abstract:What is main factor of the crustal movement? The authors of this paper believe that the universal events are one of main sources of crustal movement. There are twelve kinds of the universal events correlated with crustal movement. Among them, six types of inevitable events caused the leap tectonism by changing the otational speed of the earth. The other six types of cataclysmic events caused the sudden changes of tectonism and started the movement of the plates in the lithosphere. In geplogic history, the tectonic movement of the universal events is divided into twelve cycles by the authors. Every cycle correlates with the different types and scales of the universal and geologic events. The main patterns of the global mantle convection, the sea and the continents were moulded by four shocks of the small celestial body on the Arctic,Atlantic, Pacific and the Indian oceans.
Keywords:universal event  universal cataclysm  small celestial body sko- ck  plate tectonics  tectonism  tectonic cycle
