Taking oxygen out of the various iron oxides and the like it's locked up in sounds very energy-consuming. Also, it would be interesting to compare the composition of exposed surface material and areas further down which haven't been radiated for billions of years. Of course I refer to molecular composition, not atomic abundance which should be much the same as the exposed surface. -- Jon Leech (jon@csvax.caltech.edu || ...seismo!cit-vax!jon) Caltech Computer Science Graphics Group __@/
