Additional refinement to the [[3-D seismic: time and horizon slices|horizon-slice]] approach can be made to accommodate situations where there is growth, or differential deposition, in an interval between two interpreted horizons. For such an interval, the reflections between the two interval-bounding horizons are not parallel to either bounding horizon. To some extent, the shape of the reflections in this interval is intermediate between the shapes of the interval bounding horizons. A set of slices between the two bounding horizons, which more closely mimics the shape of the reflections in that interval, is given by
