The mineral olivine
The mineral olivine is a magnesium iron silicate with the chemical formula (Mg,Fe)2SiO4. It is a type of nesosilicate or orthosilicate. The primary component of the Earth's upper mantle, it is a common mineral in Earth's subsurface, but weathers quickly on the surface.

WebApr 13, 2024 · (Olivine is a magnesium iron silicate that has a green hue not unlike that of—you guessed it—olives.) This interaction can cause the water to be reduced to oxygen, which bonds with the iron in the minerals, and hydrogen, which then escapes into the surrounding rock. Once hydrogen has formed, a variety of natural processes can consume … WebDec 22, 2024 · “Olivine is a widely abundant volcanic mineral. It makes up over 50% of the Earth’s upper mantle, and is the most effective mineral for enabling CO 2 removal through rock weathering,” the Project’s website states. During weathering, olivine reacts with water, generating hydroxide ions that react with carbon dioxide in the atmosphere.
Webolivine , is composed of isolated tetrahedra bonded to iron and/or magnesium ions. In olivine, the −4 charge of each silica tetrahedron is balanced by two divalent (i.e., +2) iron or magnesium cations. Olivine can be either Mg 2 SiO 4 or Fe 2 SiO 4, or some combination of the two (Mg,Fe) 2 SiO 4.
