In the vicinity of the Žírovice village near Františkovy Lázně in West Bohemia there exists a striking gravimetric isometric negative anomaly. Similar gravimetric anomaly near Mýtina, about 17 km to the SE of Žírovice, was interpreted by Mrlina et al. (2009) as a Quaternary volcanic structure of a maar-diatreme type. It is possible that the Žírovice anomaly and some other similar anomalies in the Cheb Basin may also reflect Tertiary or Quaternary volcanic structures. For this reason we performed a detailed gravimetric and magnetometric survey, followed by geophysical modeling. The presence of a volcanic structure was not confirmed by this work, on the contrary, it was rather excluded. The anomaly was interpreted as a sunken tectonic 3D block/graben.
