Ground-penetrating radar evidence of faulting in unconsolidated coarse sediments

Summary This study presents the new data from the faults within Upper Pleistocene-Holocene deposits, presented by pebbles, cobbles, and boulders with a coarse-medium sandy matrix. Such sediments produce complex and diffuse wave patterns on GPR data, and it is challenging to recognise the faulting among them. Thus, we solved the direct problem of detecting fault zone features by GPR using numerical modelling. Comparing numerical simulation results with field data (GPR profiles and trench wall sketches), we proposed a summary of signs of the fault zone on GPR profiles.
