re: How does H2SO4 fit in to this
elegant sequence?
Seawater as we know it may never have been present at this site -- or any other on Mars for all we know. But some other fluid/aqueous solution likely has been, possibly still is at work in Meridiani.
So what kind of precipitates and such could occur under Martian conditions in other mineral-laden fluids?
Wonderful chart, BTW.
