Olivine is thought to be an important mineral in Earth's mantle.
Explanation:
The minerals olivine, orthopyroxene, and clinopyroxene make up the majority of peridotite, with the olive-green olivine dominating. Peridot, the birthstone for August, is a lovely crystal that is sometimes used as a gemstone. Olivine gets its name from its olive-green tint.
The olive green mineral:
- Olivine is named after its typical olive-green colour, which is assumed to be caused by nickel deposits, though it can change to a reddish tint due to iron oxidation.
Sugary,component of peridotite:
- Peridotite is a coarse-grained, dark-colored, heavy, intrusive igneous rock that contains at least 10% olivine, additional iron- and magnesia-rich minerals (usually pyroxenes), and less than 10% feldspar.
Characterstic peridotite component:
- Peridotite is an ultra-mafic intrusive rock that is thick, coarse-grained, and olivine-rich.
- It's known for having a low silica content and having little or no feldspar ( orthoclase, plagioclase). It comes from the upper mantle and is a common component of oceanic lithosphere.
