| 内容記述 | A model is presented which relates the geological and paleontological events of the past 300 million years to the Sun's passage through the spiral arms of the Galaxy. It synthesises results from different disciplines into a coherent unifying model. A simple mechanism is formulated which causally relates changes in geophysical phenomena-reversals in the Earth's magnetic field, superchrons where this cycle is suspended for long periods, polar ice variations and superplume volcanism, which gives rise to flood basalts-with astrophysical drivers from impacts and solar system penetration of interstellar gas clouds. This interrelated sequence in turn gives rise to the dramatic extinction events at the Cretaceous/Tertiary and Permian/Triassic boundaries and produces signatures associated with both cataclysmic and gradual extinctions. The question of geological versus astrophysical mechanisms for extinction are argued to be resolved into a coupled mechanism which is consistent with geological and palaeontological data so far known. | |||||
