Abstract

In the geo-information and geological studies of the last two years we has accumulated a sufficient number of geophysical, morphological, mineralogical and petrographic materials to refer the Ladoga structure to the category of the "proven" astrobleme. The identification within the Ladoga structure of the volcano-plutonic complex, which is syngenetic to an astrobleme, allows us to classify this formation as a single impact-volcanic structure: Ladoga IVS.
