Meteorite strikes may create unexpected form of silica

Piece of the meteorite Sahara 97096 (about 10 cm long), an enstatite chondrite that contains about 0.5 weight % of water. If Earth formed entirely of this material, it would have received 23 times the total mass of water present in the Earth's oceans. Credit: L. Piani, Museum of Natural History in Paris

Meteorite study suggests Earth may have been wet since it formed

They may not look like much, but CI chondrites – small fragile meteorites as shown here – are thought to be our best compositional equivalents of the bulk material of our solar system.

A schematic diagram of the Earth's deep oxygen factory shows the oxygenation and deoxygenation processes of hydrous mantle materials in the lower mantle across the ~1000 km depth beneath Earth's surface. Under the conditions of Earth's middle mantle, scientists discovered an oxygen-excess phase, (Mg,Fe)2O3+δ (0 < δ < 1) that can be formed with under-saturated water at >1000 kilometers depths. Those oxygen-excess materials may have long-termly oxidized the shallow mantle and the crust, which is essential to allow free oxygen to build up in Earth's atmosphere. Credit: Science China Press
