These two assumptions seem to be contrary to all petrologists known fact that in the active orogenic uplift, magmas of the calc-alkali series occur.

It would be highly unlikely that just an invisible piece of folded mountains is an exception, as all the mountain heights, with volcanoes, and especially the submarine mountains have normally magmas of very pronounced 'Pacific' character.
