层积砂和分级韵律层的形成-所谓的风暴砂层-发现嵌入在陆棚泥进行了讨论。随着风暴能量的减少，海岸上侵蚀的沙子被后退的沃茨带到公海，并由于波涛汹涌的大海的高波浪能量而保持悬浮状态。随着波浪能量的减少，单个悬浮云沉降，形成平行的沙层。由于通常只有缓慢的底流存在，沉积物不会重新形成波纹，而是以层积砂的形式沉积。
The formation of laminated sand and graded rhythmites — so-called storm-sand layers — found embedded in shelf mud is discussed. With decreasing energy of a storm, the sand eroded on the coast is transported away by the retreating waters into the open sea, and is retained in suspension because of the high wave energy of the rough sea. With decreasing wave energy, the individual suspension clouds settle, forming parallel sand layers. As generally only slow bottom currents are present, the sediment deposited is not reformed into ripples, but sedimented in the form of laminated sand.
