Catastrophic Events on the Terrestrial Planetary Bodies in Phanerozoic Period
Abstract
Comparative analysis of the catastrophic events on the moon, the Earth, Mars and Venus 0.037 to 1.0 b.y. ago is provided. The correlation between the intensity of cratering on the terrestrial planetary bodies and cosmic age of meteorites is shown. Synchronous splash of meteoritic bombardment of the moon and the terrestrial planets 500-700 m.y. ago is noted. That is one more indirect confirmation for the disintegration processes of large cosmic bodies in the phanerozoic period. A hypothesis is proposed that connects life explosion in this period with decay of iron meteorite parent bodies. The analysis provided shows that cratering intensity in the Earth's evolution during the last 650 m.y. strongly correlated with the beginning of different geological epochs and with 50-m.y. period in sedimentary processes.
