  abstract = {{T}his paper presents {T}rack{D}ip, a new method for dipmeter data processing. {T}his method selects, localizes and measures significant tilts from the comparison at various scales of the changes of orientation of sedimentary beddings. {W}e tested this method on simple cases (unconformity, gradual tilt, successive tilts, without and with additional random noise) and on a field example, along three sections in the {E}ocene {S}obrarbe delta, {A}insa foreland basin, northern {S}pain. {F}or synthetic data sets, the method clearly identifies and measures the introduced tilts. {O}n the field, sedimentary and tectonic structures, especially three main syn-sedimentary sliding surfaces ({S}1 to {S}3), were successfully identified from processed dipmeter data. {T}he tilt axis are mainly trending {N}-{S} in sandstones, associated to westward transport of sediments. {T}he sliding surfaces {S}1 and {S}3 correspond to {E}-{W}-trending tilt axis, tentatively correlated either to the flexural subsidence of the basin, or to anticline growth during sedimentation south of the studied area. {C}ombination of these sedimentary and tectonic directions results in a {NE}-{SW} striking submarine slope, which locally controls the gravity-driven deformations, especially on the {S}2 sliding surface. {F}inally, {NNW}-{SSE}-trending tilts above the uppermost {S}3 sliding surface are interpreted as the result of infilling on the side of the scar produced by sliding.},
