I would also add that there are many deep water (continental slope and pelagic)
Palaeozoic and Proterozoic deposits that are not oceanic (i.e. on oceanic
crust). Local (on a continental scale) examples include the Neoproterozoic
Wonoka Formation, Cambrian Parara and Mernamerna Formations in SA, the world
famous Devonian turbidites at Cape Liptrap, and the Late Cambrian cherts at
Narooma. Not a scerrick of coal in any of them. There is coal in any of the
ODP holes either, except those that have been drilled on submerged platforms
(such as the 90 east Ridge).
