Charles, if there's anything at all to the stripes, I thought maybe they could indicate the net field at the time of solidification, which could indicate which CFDL layer was rotating faster or slower than normal. And I think it could all have occurred in 26 hours as Mike calculated. We should be able to calculate approx. temperatures of magma during continental sliding and how quickly the magma surface would begin cooling below the curie temperature after exposure to ocean water. My guess is that it would cool that low quite quickly. I reckon a hellacious amount of steam must have been produced during the sliding and exposure to ocean waters. I guess it would have reduced sea levels and thus made flooding less of a problem.
I think it had to be a one-time event at that time. Only one impact site is centered within all of the known continental sliding.
