As Great Depression. Data from (Hryanina, 1999) - raised oval rim, two "central peaks", radial and concentric faults. Originally described as "trappas volcano". "The quartz grains in these rocks have signs of shock metamorphism: the cleavage, the systems of wavy cracks, likewise of planar features, partial and total isotropization of the grains, diaplect glasses and lechatelierite, crystallized. The iron spherules were noted in the pores of the sandstones." Interpreted as a result of "a simultanious impact of at least three meteorites". Coincides with the Tunguska impact site. (Hryanina, 1999) All information rather vague and writen in a low quality english. Age calibrated with (Gradstein et al., 2004).
