(After Elmendorf and Heezen, 1957.) increasingly greater application in paleogeographical reconstruction and a host of recent papers have appeared which we will not attempt to review here. It will suffice to say that Kuenen, his associates, and his students, as well as many other independent workers, have had considerable success in identifying ancient turbidity-current deposits throughout the world. There is now little doubt that turbidity currents play an important part in the deep sea (Fig. 17). Their velocities have been determined by sequences of cable breaks. The distribution of sands and silts in the deep-sea basins has conclusively shown that the abyssal plains, archipelagic plains and smooth continental rise areas owe their existence to the smoothing activity of turbidity currents. The deep-sea sands, long an enigma of geology, are adequately ex- plained by this process. It is clear that turbidity currents occur both as broad,
