Implications for early basin dynamics of the Mid-Polish Trough from deformational structures within salt deposits in central Poland

Stanisław Burliga

Abstract


In the weakly strained portions of the Kłodawa salt diapir, small scale tectonic structures developed in early stages of the diapir evolution are preserved. These are sheath folds and faults developed during gravity gliding in still horizontally layered rocks. They indicate bulk tectonic transport towards the east-towards the centre of a subsiding depression. The latter was controlled by faulting in the basement, related to NE-SW extension within the Mid-Polish Trough. The small scale structures, thus, provide evidence for the early basin dynamics.
