Petrophysics Hints at Unexplored Impact Physics

摘要: This paper deals with thermoluminescence and magnetization anomalies discovered around the epicentre of 1908 Tunguska explosion a large bolide in Central Siberia. Several mechanisms that can be caused by event influence soil level thermoluminescent emission minerals are considered. Simple estimates show strong currents magnetic fields generated through magnetohydrodynamic effects when disintegrated meteoroid is severely decelerated aerodynamic forces at terminal point trajectory geomagnetic field. Available experimental results on electrification projectiles considered relation to bolides. Debris particles moving atmosphere collect electric charges their precipitation cause lightning. Short-circuiting ionosphere Earth’s surface ionized wake discharge channels happen this case, triggering all-Earth capacitor.
