Abstract:

The dynamics of global plate migration is a very interesting project, but never solved in last fifty years. Many researchers thought that the plates must be migrated by the mantle “transporter model”, but that was not true. Due to the most of geological data were hidden in the earth, however, in the last 200 million years the geological data were more emerged, thus let us to discuss the seven models of the dynamics of global plate migrations. The authors proposed a new plate tectonic dynamics hypothesis for last 200 Ma. The solar system penetrated the galactic (Milky Way) plane in each 33 Ma and let the giant meteorites impact the Earth on the different areas with different angles to form the different plate migration models. According to this new hypothesis, the meteorite impact on Earth is a result of interplanetary gravity change in the solar system.
