It wouldn't have been buried at the time.
Evidence: http://www.bbc.com/earth/story/20141110-...flips-more These shifts leave traces in rocks. When lava cools, metal oxide particles within the rock become frozen in the direction of the prevailing magnetic field. So scientists can work out the historic positions of the magnetic poles by examining and dating lava samples.
The theory would be that when the mag field drops, the incoming solar and cosmic radiation accelerates radioactive decay and skews readings to appear much older.
Erm, I'm no physicist, but I'm fairly sure that radioactive decay rates are a constant, and not shown to be influenced by external factors. If they were, then nuclear-powered space probes wouldn't work.
