Abstract (in english)
   Anisotropy of magnetic susceptibility (AMS) and Electron back-scattered diffraction (EBSD) of magnetite and sanidine fabrics throughout an eroded trachyte lava dome in Tertiary volcanic province of the NW Czech Republic revealed two fabric types. This microfabric study suggests that the Type II fabrics resulted from collapse of vertically anisotropic trachyte crystal mush above the feeding conduit. Type I fabric is interpreted to originate from Type II fabrics by further stretching of highly attenuated fold limbs.
