Geophysical aspects of the structure and genesis of the Illinets structure have been considered in the article. New impact-volcanic concept of formation and becoming the Illinets structure have been proposed on the base of analysis of gravity and magnetic fields, experimental studies of density and magnetization of core from two bore holes together with geochronologic data, its gravity and magnetic models. In accordance with complex geological-geophysical studies in the Late Ordovician impact-meteoritic effect occurred with production of classical impact structure, which provoked, in the early Devonian in the epicenter of the blow of the cosmic body, the development of eruptive volcanic apparatus.
