The Earth''s atmospheric composition is unstable and is maintained by the biosphere. Namely, the large amount of free diatomic oxygen is maintained through solar energy by the Earth''s plants, and without the plants supplying it, the oxygen in the atmosphere will over geological timescales combine with material from the surface of the Earth.

Harder stones may be worth processing, especially if they have unique colors. Clays can make good pigments, but not always; you can dig them out, let them dry, remove any large or hard rocks or organic matter and grind them after levigation. Each geology and ecosystem has something different to offer you, and it requires a lot of experimentation.
