Anotace	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. The high degree of AMS fabric is associated with sanidine textural domains similar to normal kink bands and occupies the whole body except the SW margin. Folded fabric and low anisotropy of AMS also in the SW margin reveals sanidine alignment domains resembling reverse kink-bands. The flow of trachyte lava occurred via simultaneous slip of sanidine crystal along their planes and also by readjustment of the textural domain boundaries according to the fibre-slip theory.
