|Carbonate buildups are often considered to form in relation to faults. Based on seismic data it is often hard to distinguish between faults beneath carbonate buildups and seismic artifacts due to velocity contrasts between carbonate buildups and their surrounding sediments.
In an interesting study based on 3-D seismic data, Bailey et al. (2003) conclude that discontinuities beneath carbonate mounds offshore Ireland are indeed such seismic artifacts.
