# On the problem of the Tunguska meteorite material

O. G. Gladysheva, 2007. _Solar System Research 41(4), 314–321_.

Averages measurements of the presumed remnant material, finding it enriched in alkali and alkaline-earth elements and very heterogeneous, and estimates an upper density limit of 2.8 g/cm³ with disintegration into 10⁻⁷ to 10⁻³ m particles.
