User:Licks-rocks/sandbox/Carbonate ramp

A carbonate ramp is a type of carbonate platform that forms a very gradual slope from basin floor to shoreline, with a slope angle below one degree. They can commonly reach slope angles lower than 0.1°. Carbonate ramps lack the rimmed shelf typical of other carbonate platform types. Instead of the distinction between lagoon, reef, and open marine, Carbonate ramps are typically separated in an upper section, a middle section and a bottom section, identified by their relative depth below the sea surface.
