THE DEGASIFICATION MODEL OF PLANETARY EVOLUTION AND THE SCHEME OF PLANETARY EVOLUTION FOR EARTH

Planets are born, live and die. And the different processes correspond to the different stages of planetary development. The processes of gravitational differentiating of planet's substance have maximally variability during planetary evolution. The gravitational reallocation of substance occures since the moment of planet's derivation - heavier components tend to displace more light components. In the long run development of this process determines evolution of planetary degassing processes. Volcanic and magmatic activities can be considered as the forms of planetary degassing processes. It is possible to assume, that the following stages of development are probable for Earth with its larger degasification potential and with continued endogenic processes : 1. Epoch of panplanetary degasification and universal magmatectonic activity which was resulted in the formation of protoplanetary (protooceanic) crust. 2. Epoch of localization of degasification and magmatectonic processes within large planetary areas. It was resulted in the creation of protocontinent (or protocontinents) and most ancient platforms of Earth. 3. Epoch of localization of degasification and magmatectonic processes within lengthy girdles of boosted endogenic activity (plastic plate tectonics). 4. Epoch of mainly linear localization of degasification and magmatectonic activity which was resulted in cracking Earth protocontinents and creation of spreading and subducting structures on its surface (hard plate tectonics). 5. Epoch of mainly hot spot degassing. 6. The epoch of complete termination of gravitational-differentiational processes in depths of the planet, and appropriate termination of manifestations of magmatectonic processes on its surface. Now Earth is on 4-th of set forth above stages of development. The further analysis both the evolutions of other planets and Earth geodynamic structures will show as far as these working schemes are right.
