This response shows a misunderstanding of what I suggest has happened. Please read my posts on the subject. The hydrogen once released would permeate to the surface. Some would react. Some would escape into space. A slow process. The emergent atomic hydrogen would react for example with carbonates to produce water (seas) and hydrocarbon. Plus some molecular H2 may be trapped, or still permeating thru.

Pangea or Rodinia cannot account for the perfect match of the jigsaw across the Pacific. The match across the Atlantic was caused by the continents ripping apart. The equivalent match across the Pacific must have the same cause.

Once again
