摘要
从大陆漂移与板块形成是白垩纪末太平洋部位遭遇撞击的结果出发,阐述了1颗半径约680 km左右带冰块为主的星体向西略偏南斜向撞击地球,其主要撞击部位大约在东经139°、北纬17°西马里亚纳海盆内.
It is presumed that the drift of the continents and the plate formation were all resulted from the site of Pacific Ocean being impacted in the late Cretaceous.Based on this point of view,it is described that a star with the specific radius of about 680 km and a bit more ice hit the Earth in the direction of west but a slightly southern deflection and the main impact site was at about longitude 139 °,latitude 17 °,in the West Mariana Basin.
