AB: Hundred years ago an unknown object impacted in Siberia, Tunguska
region and created a seismic signature 100-1000 times stronger that the
Hiroshima explosion. To this day, nothing has been found to suggest a
foreign material (e.g. meteoritic) dispersion during this event.
Various hypotheses were put forward, for example: Comet impact,
Kimberlite Pipe explosion, and Mirror Matter interaction with the
regular matter. We collected samples of black chert, conglomerate and
wood from 5 different locations within 2 km from the epicenter. We used
these samples for magnetic analysis and searched for any evidence of
magnetic contamination that may date the Tunguska blast. All samples,
wood, chert, and conglomerate showed sufficient content of magnetic
material that should be capable of recording strong magnetic pulse. Our
analysis shows no evidence of magnetic enhancement recorded in any of
the three types (Chert, wood and conglomerate) of Tunguska samples. We
will discuss this result in terms of three possible hypotheses of the
created the Tunguska event.
