| Abstrakt: | Abstract: The local magnetic maxima near the village Rájov (NE of Mariánské Lázně) revealed by airborne magnetometry was further surveyed using ground gravimetry and magnetometry. The measured magnetic data revealed a positive magnetic anomaly in the centre of the surveyed area. The measured gravity data showed two small-scale gravity minima. The geophysical data are interpreted by a presence of the maar-diatreme volcano, basic intrusions, and a lava flow filling the maar crater. The overall interpretation suggests, that volcanism in this area probably started with the phreatomagmatic eruption of the Rájov maar and then continued with the Strombolian eruption of the nearby Podhorní vrch volcano. |
