Abstract

Ozone in the rocks: A clathrate hydrate can be formed from an O ₃+O₂+CO₂ gas mixture (see picture, left; O ₂+CO₂ hydrate is shown for comparison). The pale blue color of the former is probably due to the ozone molecules encaged within. The O₃+O₂+CO₂ hydrate stored in air at normal pressure at -25 °C can preserve ozone (0.1 % in mass fraction) for over four weeks.
