The recent paper of Siebel et al. (2008
) provides useful geochemical and geochronological data for Variscan granites from the large and previously little studied Bavarian Forest sector of the South Bohemian Batholith (SW Bohemian Massif). We agree with several of the geological conclusions reached in this paper, but would like to comment here on one specific point, where we hold a significantly different opinion. This concerns the conclusion of Siebel et al. (2008
) that the Pfahl fault (see Siebel et al., 2008
, fig. 1) represents an important plate-tectonic boundary within the SW Bohemian Massif and separates basement terranes of different composition. A terrane map of that kind has been published by Fiala et al. (1995
), who introduced the term Bavarian terrane
