Numerical simulations show that stony meteorites with masses in the 10*8 to 10*11 kg range may undergo total disruption during atmospheric entry in the lower layers of the Earth’s atmosphere, in a similar manner to the Tunguska event that occurred over Siberia in 1908 [12]. Modelling also show that at a later stage of a Tunguska-like impact a plume of hot vapour and ablation debris is created, which will ballistically expands at high altitude over areas extending for some thousands of km in radius, to then decelerate by gravity at lower altitudes producing a regional fallout of plume material [13]. We thus speculate that a plume similar to that modeled for the Tunguska event could have been responsible for the continental scale distribution of the ablation debris found at Miller Butte, Dome C and Dome Fuji.  — M.
