* Oxygen is the most [[abundant element]] on Earth (crust on surface). It's roughly on par with iron when looking at the whole Earh including the inaccessible interior. (The whole earth average may be a good representation of the elements distribution in the better accessible asteroid belt).

This article is a stub. It needs to be expanded.

Oxides

(TODO: discuss major ones here)

Carbon group / group IV / group 14 oxides

  • CO2 normally the well known gas but highly explosive when in solid sp3 form (analog to quartz)
  • SiO2 quartz and its various known polymorphs (~Mohs 7)
  • GeO2 argutite Mohs 6-7 -- germanium is a rather rare element!
  • SnO2 cassierite Mohs 6-7
  • PbO2 [1] -- alpha-PbO2 scrutinyite -- beta-PbO2 plattnerite (TODO: find out Mohs hardness of PbO2 minerals)

(All those have rutile structure. See page about silicon.)
(TODO: Here maybe some pseudo phase diagrams can be made.)
