To understand how water affects subduction of the oceanic plate, in which layers of different rock types sink into the mantle, the UO team studied hydrogen isotopes in water contained in tiny blobs of glass trapped in olivine crystals in basalt. (sciencedaily.com)
This stunningly distinctive characteristic is the cause of olivine crystals created from volcanic activity. (best-beaches.com)
One paramount goal: completing his collection of pallasites, pretty meteorites that often contain green olivine crystals suspended in a gray matrix like luminous polka dots. (science.sciencemag.org)
