VULKANOKLASTIKA STŘEDNÍHO BADENU VE VRTU OS-2 HAŤ U HLUČÍNA (SLEZSKO)

Slavomír Nehyba

Abstrakt

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