Additional refinement to the [[3-D seismic: time and horizon slices|horizon-slice]] approach can be made to accommodate situations where there is [[growth fault|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
