The Doupovske Hory Volcanic Complex (DHVC) is the bestpreserved large volcanic suite of the Cenozoic intraplate volcanism in the Bohemian Massif. However, many uncertainties remain in the geological setting of its basement. In summer 2008, two seismic refraction profiles ran across this area to reveal the depth of the volcanic rocks and the underlying geological structure. A high-velocity body was detected beneath the central part of the DHVC at depths of about -500 m a.s.l., inclined to the NW at an angle of about 45°. This body is most likely formed by the basic and ultrabasic rocks (amphibolites, eclogites, serpentinites, metagabbros) of the Equivalent of the Marianske Lazne Complex (EMLC). Subvolcanic rocks of the DIC penetrating these basic and ultrabasic metamorphic rocks have very similar physical properties. Therefore, intrusive body of the Doupov Intrusive Complex (DIC) can be hardly distinguished from rocks of the EMLC by seismic refraction investigation.
