Mercury Content from the Tunguska Meteorite Craters and in Some Siberian Towns

摘要

This paper presents the results of research into mercury concentrations in the samples taken from three craters located in the explosion epicenter of the Tunguska meteorite. In 2009 and 2010, several expeditions were conducted using ground-penetrating radar to study the structures of 40 craters. Boreholes were drilled at seven craters. Mercury content in samples obtained during drilling was evaluated. Data on mercury content at natural sites of other regions of Siberia are provided for comparison.
