the Kataklysmentheorie (lat. cataclysmus too griech. kataklysmos: Inundation) designates a geoscientific doctrine 18. and 19. Century, which itself the sequence observed within the layers of the earth's crust world-wide disasters (Kataklysmen), repeated of organisms and partnerships as result of, (see Katastrophismus) with following in each case new creation thought.
The most exposed representative of the Kataklysmentheorie was a French scientist Georges Cuvier. Only the British geologist Charles Lyell introduced the principle of the Aktualismus to the geology, which it means that in geologic history only such forces at the organization of the earth had worked, which are to be still observed also today. The often abruptly working transitions between different Schichtfolgen and Faunenschnitte the Aktualismus explains not as result of sudden and briefly continuous world-revolutionary disasters separates as excessive quantity gaps and as consequence to that extraordinarily is enough for duration of geological processes. The Aktualismus was one of the conditions for the development of the evolution theory Charles Darwins.
A surprising revival of the conceptions of the Kataklysmentheorie and thus a relating of the principle of the Aktualismus brought in the second half 20. Century the actually world-wide disasters of all-largest extent it caused the realization that the earth, like other heavenly bodies also, was exposed in their history many marks to the impact of large meteorites, Asteroiden and comets.
For some years the references mehren themselves that apart from cosmic disasters, like Asteroiden and comet hit, radiation outbreaks of near earth new fact or supernew facts - events, course changes in the solar system and other, also ground-based procedures planet-far changes in the sense of the Kataklysmentheorie, engraving at short notice, to cause can. In addition for example Calderenausbrüche (Yellowstone - Caldera) with following count volcanic winter, tearing off important Meeresströmungen (gulf stream) with following ice age and superearthquake and associated Tsunamis.
