Where is olivine found in the world?

Typical Location Olivine is often found in dark-colored igneous rocks found in the surface of the Earth. These rocks are often located in tectonic plates and divergent plate boundaries. Olivine has a high crystallization temperature which makes it one of the first mineralize to crystallize from the Earth’s heat.

Is olivine rare on Earth?

Olivine is one of the most important minerals used to reconstruct magmatic processes, yet the rare earth element (REE) systematics of Fe-rich olivine in igneous rocks and ore deposits is poorly understood.

Where is olivine most abundant?

The most abundant olivines occur in the system from forsterite (Mg₂SiO₄) to fayalite (Fe₂SiO₄). Most of the naturally occurring olivines are intermediate in composition to these two end-members and have the general formula (Mg, Fe)₂SiO₄.

Is olivine found in Australia?

Olivine is green to olive green, yellow brownish-red when oxidised. It occurs in basic igneous rocks low in magnesium and silica. In Australia two main locations are noted-one Station on the Kennedy Development Road in Queensland and Mortlake in Victoria.

Which layer of the earth is rich in olivine?

upper mantle

Because the rocks of the upper mantle directly below the Mohorovičić discontinuity (Moho) are believed to consist of peridotite and garnetiferous peridotite that contain olivines as their most abundant minerals, it is important to establish their behaviour when subjected to high pressures.

Is olivine a rock or mineral?

Olivine is one of the most common minerals within the earth, and is a prime rock forming mineral. Despite this, desirable specimens and huge crystals are unusual and fashionable. Only few localities yield large examples of this mineral, even though small and microscopic grains are determined worldwide.

Chemical Composition

Olivine receives its name from its usual olive-green color.

Where do you find peridotite?

Peridotite is the dominant rock of the upper part of Earth’s mantle. The compositions of peridotite nodules found in certain basalts and diamond pipes (kimberlites) are of special interest, because they provide samples of Earth’s mantle brought up from depths ranging from about 30 km to 200 km or more.
