Topband: Future propagation ?

[K1FZ-Bruce]

 Watching NOVA on PBS last night.  Diving into Blue water "sink holes".  Found evidence indicated that iron rich sand from the very dry Sarah Desert had blown across the Atlantic to the Bahama Island region. 
(possibly related to previous global warming period ?)
 
Wondering, if this takes place again, will this semi conductive  material give us a leg up on propagation to Africa, and beyond ? (;>))
