The fact of Tunguska explosion in Siberia is known already during 100 years and many scientists try to explain this event
from position of asteroid or comet impact. In 1988 three stones were found by A.E.Zlobin, which he determined as
probably Tunguska meteorites recently.
Due to chaos caused by USSR disintegration, Zlobin had not possibility to investigate these stones with necessary laboratory conditions
and experimental equipment. It was possible only intensive investigation of Tunguska event with methods of mathematical modeling.
However, a lot of new results were obtained by Andrei Zlobin with the help of computers during last decades.
Total energy of Tunguska catastrophe was concretized with more detailes from position of destruction of four fragments
of comet's nucleus in the atmosphere. Form of trajectory, azimuth direction and inclination angle was confirmed in accordance
to informative data of eyewitnesses and due to most reliable studies by earliest investigators
(L.A.Kulik, I.S.Astapovich, E.L.Krinov and others). Main heat processes became clear and the area of forest burn (picture above)
was explained from position of local impacts of fragments of compound comet nucleus (picture below).
quasi 3-D modeling of Tunguska impact several places were determined, where falling of meteorites was possible.
One of these places not far from Pristan camp coincided to Zlobin's discovery of three melted stones in 1988.
All these results you can find in papers of A.E.Zlobin.
Also Zlobin's opinion were mentioned by academician N.V.Vasilyev in his last monography concerning the Tunguska phenomenon of 1908.
In 2013 A.E.Zlobin continued cautious investigation of three probably Tunguska meteorites with different laboratory methods.
First of all that methods is used, which not require destruction of samples. Attentive analysis of form, size, weight, color was carried out.
All three stones were investigated with the help of high resolution magnifier and described with mention of many detailes.
Additional mathematical modeling was carried out for determination of conditions of stone's melting. During summer of 2013,
first investigation of substance of stones was carried out and the presence of traditional cosmic marker of meteorites was confirmed.
Concentration of substance of this marker was estimated without destruction of samples.
The investigation of three probably Tunguska meteorites is being continued now, and determination of density of stones is planned.
