Giant beds - impact induced deep-marine deposits

Deep sea is typically considered as low energy environment, where basinal sediments have very good preservation potential. However, we frequently see evidence of very high-energy events in deep-sea sequences, in form of exceptioanlly thick beds - commonly referred to as megabeds or megaturbidites. These were obviously induced by exceptional causes, because the rest of the sequence is composed of much thinner beds. The number of such thick beds differs from one basin to the other, as well as the criteria for their definition; some authors define certain minimal thickness, whereas some other define a set of several criteria amongst which is thickness. In some basins nmegabeds account for significant part of the succession, but sometimes there occur rare beds which are exceptionally thick, even by criteria of megabeds, and these will be referred to as giant beds. I strongly believe that all of these beds were initiated by a common trigger, which must have been of very high magnitude, singe the area of their occurrence is presently 120 km long, and about 20-45 km wide. An impact trigger is preferred in this case because it can create sufficient high-magnitude and high-acceleration tremor, which will affect very wide area.
