where did the nuggets come from?
Almost everything around us originated in exploding stars - presumably the violence of a supernova would have produced clouds of matter separated at the atomic level.
If that is the case, how come we get nuggets of pure gold, mountains of iron, hills of uranium ore etc. - what mechanisms have caused materials to cluster and how does this relate to the second law of thermodynamics?
Not trying to make a point - am just curious - any geologists out there?
