That sounds very plausible, but so far you haven't brought Shock Dynamics into the picture. Have you? According to that the seafloor magnetic striping occurred over a period of 26 hours. Furthermore, I've read that the striping is much more chaotic on the seafloor than it appears on the ocean surfaces.

Does this mean that the Shock Dynamics event, i.e. the huge impact and the aftermath, caused disturbances in the CFDLs, which resulted in the chaotic seafloor magnetic striping?

Is there any reason not to discuss the impact scenario in the TB forum thread?
