  I depends upon the geological fractal you're talking about.  Mountains may
be seen as 2.x dimensional, and clouds as zerosets of 3.x dimensional fractals
(as the coastline is the zeroset of a mountain).  So you may already invoke
a fractal dimension greater than 3 in a geological structure, even without
taking time into acount.

  I'm trying to imagine a phenomenon with the same statistical beavior in time
as in space...  Can you be more specific?
