Abstract

Middle Badenian tefra has been recognised within the drill hole OS-2 Hať drilled within the deposits of the Carpathian Foredeep in the North Moravia. Pumice shards of volcanic glass predominate over the cuspate shards in the studied sample. Source volcanism can be described as rhyolitic based on volcanic glass chemistry. Study of volcanic zircons reflects relative high eruption temperature (800oC) and hybrid character of parental magma. Zircon characteristics are significantly different from the previously studied Neogene volcaniclastics of the Carpathian Foredeep. Studied Middle Badenian volcaniclastics can be described as distal ones and their source and origin is most probably connected with areal type of acidic volcanic activity in the Carpatho-Pannonian region.
