There is olivine within the mantle, but it typically occurs at shallower depths (less than 400 km) as at greater depths than this the pressure causes olivine to become unstable forming what are known as high pressure poly-morphs! These have the same chemical composition but a different crystal structure.
The Earth's upper mantle has a composition similar to the green mineral olivine. Olivine is a common mineral found in the upper mantle, making up a significant portion of its composition.
The most abundant component of mantle rocks is silicate minerals, such as olivine, pyroxene, and garnet. These minerals make up the majority of the Earth's upper mantle and are rich in magnesium and iron.
Olivine is a common mineral found in the earth's upper mantle, which is located between the crust and the lower mantle. It is brought to the surface through volcanic activity in the form of lava or magma.
The Earth's mantle is primarily composed of silicate minerals rich in magnesium and iron. The dominant mineral types include olivine, pyroxenes, and garnet, with olivine being the most abundant at the upper mantle. The mantle also contains other minerals like peridotite and eclogite, which can form under high-pressure conditions. Overall, these minerals contribute to the mantle's properties, including its ability to flow slowly over geological time.
Mercury's mantle is mostly made up of silicate minerals, similar to Earth's mantle. This layer is believed to be composed of magnesium silicates like olivine and pyroxene.

Olivine.
The Earths mantle is filled with ferromagnesian rocks with minerals such as Olivine and Pyroxene.
The earth's lower mantle is composed of an olivine mineral with a perovskite structure.
The most abundant component of mantle rocks is silicate minerals, such as olivine, pyroxene, and garnet. These minerals make up the majority of the Earth's upper mantle and are rich in magnesium and iron.
Olivine is a common mineral found in the earth's upper mantle, which is located between the crust and the lower mantle. It is brought to the surface through volcanic activity in the form of lava or magma.
The lower layer of the mantle is composed of solid rock that is under high pressure and temperature conditions. This layer is known as the lower mantle and is made up of silicate minerals such as peridotite and olivine. It plays a significant role in Earth's mantle convection and the movement of tectonic plates.
The upper mantle is primarily made up of silicate minerals such as olivine, pyroxene, and garnet. These minerals contain elements like silicon, oxygen, magnesium, and iron. Olivine is the most abundant mineral in the upper mantle.
The uppermost mantle rock is Peridotite, which is mostly olivine and pyroxene but varies somewhat in chemical composition. Generally it is a coarse grained greenish rock. The name peridotite is derived from the gemstone peridot, which is pale green olivine.
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
