||Topographic seafloor structures that are the result of previous periods of coral growth,
often with successive periods of reef development, sedimentation, and erosion. These
are elevated structures, composed of coral fossils and accumulated interstitial sediments.
This type includes structures variously referred to as carbonate knolls, coral banks,
bio-buildups, and lithoherms. Coral carbonate mounds can take on various shapes and
sizes, reaching tens of meters in height and tens of kilometers in size. They may
or may not currently include biogenic reefs (Roberts et al. 2009).
