Anotace

Soft-sediment deformation have been newly recognized within the Lower Badenian deposits of the Carpathian Foredeep in the outcrop near Oslavany. The deformed unit is sandwiched between undeformed foreshore deposits. Medium to fine, fine and very fine grained sands reveal a conspicuous lithological similarity of deformed and undeformed unit. Deformations structures have been grouped into two categories i.e. contorted and intruded ones. The contorted structures consist of convolute folds, contorted lamina sets and pillow-shaped structures. Cusps, dish and pillar structures, and sand injections represent the intruded structures. The deformation mechanism is interpreted to be due to liquefaction/fluidization and seismic activity in the area under study is assumed to be the trigger mechanism.
