Olivine: A rock-forming mineral. Used as the gemstone peridot.

Olivine in Earth's Mantle. Olivine is thought to be an important mineral in Earth's mantle. Its presence as a mantle mineral has been inferred by a change in the behavior of seismic waves as they cross the Moho - the boundary between Earth's crust and mantle.. The presence of olivine in Earth's interior is also confirmed by the presence of olivine in xenoliths, which are thought to be pieces ...

Rock seen inside Venus's orbit could solve puzzle | Science

Jul 03, 2020· Earlier this year, astronomers discovered an oddball asteroid inside the orbit of Venus—the first member of a predicted flock near the Sun. No bigger than a small mountain, the asteroid has now gained another distinction: It appears to be rich in the mineral olivine, which makes up much of Earth's deep rock. Some astronomers think that is a clue to a larger set of asteroids, never properly ...

Purdue University :: Olivine Separation

Olivine Separation. Normally, olivine separation is not done. However, olivine can be rapidly separated from rocks such as basalt using a variant on the froth flotation method known as grease tabling. Grease tabling is commonly used in the diamond mining industry because diamonds are naturally hydrophobic. A sample with a high olivine content ...

Olivine Group: Mineral information, data and localities.

Hemy C. Salmon in 1859 explicitly used "olivine group" to designate minerals which were chemically analogous to "olivine". In the USA, James Dwight Dana and George Jarvis Brush began organizing groups in their "System" and organized the "chrysolite group" in 1868 and that group name was continued into 1892 by Edward Salisbury Dana.
