Clay diapirs in Neogene-Quaternary sediments of central Sicily: evidence for accretionary processes

The Neogene-Quaternary sediments infilling the perched basins of the central Sicilian thrust belt are characterized by the occurrence of several lenticular bodies of mud breccia. These bodies, made of a brecciated to cataclastic clayey matrix containing exotic blocks, represent the result of mud diapirism occurring along the frontal part of the central Sicilian accretionary wedge.
