| 11. | Hence, garnet peridotite must have been formed at great depth in the earth.
|
| 12. | Layered peridotites are igneous sediments and form by mechanical accumulation of dense olivine crystals.
|
| 13. | The crust and the relatively rigid peridotite below it make up the oceanic lithosphere.
|
| 14. | These blocks of mantle peridotite and the metamorphic eclogites are exposed as ophiolite complexes.
|
| 15. | The Wenatchee Mountains are mostly composed of peridotite.
|
| 16. | Naturally reacts with peridotite rock in surface exposures of ophiolites, notably in Oman.
|
| 17. | Rock types include picrite, peridotite, dunite, pyroxenite, gabbro and granophyre.
|
| 18. | Peridot explains that it is superheated liquid peridotite, a material similar to peridots.
|
| 19. | Only 0.6 % are syenites and 0.3 % peridotites and dunites.
|
| 20. | The chromite bands found in peridotites are the world's major source of chromium.
