Figure 2. Manual tracking of the unconformity as a seismic horizon is straightforward where the unconformity is most clearly angular. The suggested practice is for the interpreter to pick this area first, as shown by the yellow horizon, and then decide how to pick into the areas where the unconformity is layer-parallel and can be autotracked (data quality permitting). This entails determining whether the unconformity is a peak (red) or a trough (black), which indicates the sign of the acoustic-impedance contrast across the unconformity as positive or negative, respectively.
