Abstract

This paper summarizes the results of application of the anisotropy of magnetic susceptibility in tephrite lava flow in the Vrbička quarry (Doupov Volcanic Complex). This method was applied in order to determine the sense of the lava flow direction, estimate its volume and to interpret possible volcanic center. The E or NNE dipping magnetic lineations roughly correspond to the lava flow movement in this direction. Such geometry indicates the vent located E or NE - probably at Chlum or Kruzin Hills, or unknown volcanic centre in the SE.
