Abstract
(English)
Abstract Morpho-bathymetric and stratigraphic data reveal small-scale mud reliefs in the toe region of the late-Holocene mud wedge on the Adriatic shelf. The reliefs are elongate features with acoustically-transparent cores. They are present in two geologic settings: seaward of shore-parallel undulations within a thick mud wedge and seaward of basement highs where the mud wedge is thin. In both settings, the reliefs define clusters sub-perpendicular to the regional contours, possibly indicating an origin related to escape of fluids from an impregnated unit at the base of the late-Holocene wedge. Shore-parallel bottom-hugging currents appear to modify the reliefs following their episodic growth.
