A display made from a 3D data set of the data elements that lie on the same picked reflecting horizon, thus showing areal variations in amplitude or other attributes (such as dip magnitude or azimuth). Usually made by slicing through the 3D volume parallel to a nearby picked horizon that is believed to conform with it. Also called an amplitude map where it displays amplitude. Different from a horizontal slice (time slice, q.v.); see also Figures H-8 and T-5. Also called a surface slice and sometimes a ‘‘geological time slice.’’
