The work is focused on the analysis of the morphology, chemical composition and stratigraphic distribution of fossil micrometeorites - of small cosmic bodies recorded in the sedimentary sections of different age and origin. The penetration to the Earth a large of the number of small cosmic particles (Micrometeorites Events) is proposed to consider as an important process of the infl uence of the Earth from the Space, that similar with the fall of large meteorites (Impact Events). At this paper provides the update scheme of Impact Stratigraphy of Phanerozoic and the marked of the stratigraphic levels the different types of micrometeorites, tektites, mikrotektites and microkristites, which were found in sedimentary deposits.
