Firstly, many astroblemes are spatially connected with unique deposits of diamonds, gold, polymetals, and some other things [1–3 etc.]. Secondly, it is difficult to overestimate the influence of catastrophic explosions of space objects in the past on the formation of the modern topography of the Earth. In the Siberian Platform, reliable compositional features characteristic for impact structures are estab� lished only for the Popigai meteorite crater [4]. In the
