Thanks very much Carl - did some reading on lines you suggested and now have a better understanding of mineral concentrating mechanisms. Appreciate your reply.
What I still have trouble with is the way that a very well organised solar system has condensed from a dispersed cloud of matter. And some of the minerals in the earth have even pulled themselves together into organised structures under the action of natural processes (and of course living systems are highly ordered). This goes against all that I thought I knew about time and order - what happened to entropy in this process? Is it possible that the order we now see was inherent in the cloud of matter and has been "expressed" somehow by the action of gravity - or has local entropy reduced - or what?
regards Ray
