So have you actually observed the trasport of this sediment? Is the sediment labeled "imported from the Pacific Ocean? What we do know is that you are wholesale ignoring geology, including references already provided to you last year.
This whole how thread is a redux of the previous year’s Geological Megasequences where was explained why giant tsunami’s were not the origin of the Sloss megasequences, including the statement by the man himself:
L. L. Sloss, 1964, Tectonic Cycles of the North American Craton:
The writer concludes that the history of the North American craton for the past 600-700 million years includes six major episodes of changing tectonic behavior.
The whole transport idea is incoherent. Why would one ocean have sediment and the other not have it’s own, to begin with? Furthermore, a great deal of the sedimentation of the central plains is erosion from the Rockies.
