Fig. 3.20.— The Otway shelf of southern Australia, the landward end of a cool-water carbonate factory. Swell with wave lengths of 50
– 100 m breaks on the shoreface. On a tropical platform such waves (that feel bottom at 25 – 50 m) would be absorbed by the offshore
rim of reefs or sand shoals. Photo by N.P. James.

Fig. 3.21.— Paleozoic mud mounds in the Algerian Sahara that formed on a ramp in an epeiric sea. The exquisitely preserved mounds
in this photo are tens of meters high and over hundred meters in diameter. The rounded tops as well as biota and sediment facies suggest
that even the crests lay below wave base. Photo by B. Kaufmann
