by its color. the color green like an olive.
Sand is formed from the breakdown of rocks. If a rock contains large amounts of olivine, then when this rock weathers, olivine sand will be formed. There are beaches in New Zealand that are almost exclusively made of green olivine crystals.
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.
Mafic, igneous rocks
Peridot is a gemstone composed of the mineral olivine. Olivine is a common mineral found in igneous rocks such as basalt and peridotite. So, while peridot itself is not an igneous rock, it is closely associated with igneous rocks due to its mineral composition.
Ultramafic igneous rocks are comprised mostly of olivine and pyroxene. Examples include peridotite (pegmatic and porphyritic) and komatite.
Dunite is not a common rock but olivine is.
No. It is olivine, which is a mineral.

Olivine is found in space rocks so it is certainly present in all the rock planets.
It's found in Meteorites
Mafic, igneous rocks
Mining deep in the Earth cores. Mining deep in the Earth cores. You can also find Olivine in the Igneous rock Pyroxinite. Olivine is the same thing as Peridot
