Holocene activity of the Mariánské Lázně Fault (Cheb basin, Bohemian Massif): youngest proved surface faulting in central Europe?
2015
Abstract
The NNW-SSE trending Mariánské Lázně Fault (MLF) zone is situated in the western part of the Bohemian Massif (Czech Republic). It is morphologically very pronounced and limits the Tertiary Cheb basin on the SE.
Trenching survey with shallow geophysics (electric resistivity tomography, ground penetrating radar) was combined to study the late Quaternary activity of the MLF. Trenching revealed repeated movements along the several faults of various ages within the MLF on the Cheb basin limit.
The youngest fault cuts and deforms young Holocene deposits of the age interval 5.3-1.1 ka BP, which is the youngest proved surface faulting in central Europe reported so far.
