Is this all trying to say that mountains are just fossilized sand? That is certainly a .. novel... theory of geology.

Fossilization of organic matter generally takes about 10k years, give or take. Fossil is a word that tends to encompass a lot of things though, so it depends.

Still, the amps that you'd have to pump through a dune to get it all to melt/solidify would be astonishing. Think a constant lightening bolt for years on end. Most sands are insulators afterall.
