Abstract (in english)
   The following Cenozoic alkaline volcanic rock series were recognized on W Bohemia: Oligocene-Miocene (31-20 Ma) volcanic of the Ohře Rift, 1.1. the Doupovské hory Mts. with unimodal series of ol. nephelinite - basanite to tephrite - (phonolite) (31-26 Ma), 1.2. the Ohře Rift region between the Doupovské hory Mts. and the Mariánské Lázně Fault Zone with the unimodal series of (melilite-bearing) ol. nephelinite - tephrite (24-21/16). 2. Middle to Late Miocene (17-8/7 Ma) volcanics of the Tepelská vrchovina Highland and Slavkovský les Mts. developed in two coexisting series: 2.1. weakly alkaline series: basanite? - trachybasalt - (basaltic) trachyandesite - trachyte - (rhyolite) (15.9/12.8-11.4/6.5/ and 2.2 strongly alkaline series: (melilite-bearing) ol. nephelinite - tephrite (16.5-8.3 Ma), 3. Quaternary (0.4-0.1 Ma) volcanics of the Cheb area at the junction of the structures of the Ohře Rift and the Cheb-Domažlice Graben with (melilite-bearing) ol. nephelinite.
