Why does olivine appear green?
Olivine appears green because of its iron content. The iron in olivine absorbs certain wavelengths of light, especially in the red part of the spectrum, giving it a green hue. This characteristic color is why olivine-rich rocks like peridot have a distinct green color.
What are three most useful properties of identification for olivine?
Olivine has a distinctive green color, making it easy to identify visually. It has a high hardness of 6.5-7 on the Mohs scale, aiding in its differentiation from other minerals. Olivine often occurs in tabular or elongate crystal shapes, which can help distinguish it from similar minerals.
What is the light green birthstone called?
The "Peridot(Olivine)" is the light green August birthstone.
Where is olivine mined?
Olivine is mined in various countries around the world, including the United States, Norway, Finland, and India. Some of the major olivine mining locations include Hawaii (forsterite-rich olivine), Norway (fayalite-rich olivine), and Finland. These regions have significant deposits of olivine due to their geological history and processes.
Why are some volcanoes green?
Some volcanoes appear green because of the growth of mosses, ferns, and other vegetation on their slopes, which thrive in the nutrient-rich volcanic soil. The green color is due to the chlorophyll in the plants, which reflects green light. It can also be caused by minerals such as olivine, which is green in color.
How did an olivine rock got its name?
Olivine rock got its name from its olive-green color, which comes from the mineral olivine found within it. Olivine is a common mineral in the Earth's mantle and is often found in igneous rocks like basalt and gabbro.

What is the upper most mantle rock like?
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.
What rock contains high density minerals such as olivine?
Mafic, igneous rocks

What is a peridot composition?
Peridot is composed of the mineral olivine, which is a silicate mineral made up of iron and magnesium. It has a molecular formula of (Mg,Fe)2SiO4. The vibrant green color of peridot is due to its iron content.

How many members of olivine group of minerals with details?
four common members of olivine family that is 1) FORSTERITE ((Mg) 2SiO4.2) fayalite(Fe) 2SiO43)olivineMn SiO44) tephorite( Mn2SiO4)
What is the color of dunite?
Dunite is typically a dark green to olive-green color due to its high concentration of the mineral olivine.
Why do biologists think that ancient green algae were ancestors of today's plants?
Because their basic cellular composition remains similar to the modern plants.
