Possible mechanisms relating asteroid impacts to extinctions and geomagnetic reversals
Abstract
Mechanical processes occurring between the crust and the interior of the Earth, which overcome the difficulty in relating sources of the geomagnetic field dipolar component and shallow asteroid impact effects, and which help to explain some points about the causes of the Earth's magnetic field and its reversals, are discussed.
