Translations:Picking unconformities/10/en

From the preceding discussion, it is clear that as a single surface, this unconformity is composed of different segments which alternately are tracked manually and automatically. Fortunately, most interpretation applications allow this for a single horizon as long as the waveform onset type for autotracking, that is, peak or trough, does not vary spatially — it can be one or the other, but not both (zero crossings are omitted from this discussion). If the waveform onset type does vary, as in this example, the unconformity must be tracked on separate horizons as a peak or trough, and the composite horizon must be built by merging these component horizons.
