Olivine is the name of a group of rock forming minerals that are typically found in mafic and ultramafic igneous rocks such as basalt gabbro dunite diabase and peridotite They are usually green in color and have compositions that typically range between Mg 2 SiO 4 and Fe 2 SiO 4 Many people are familiar with olivine because it is the

Olivine tolerates well pressures in the crust and in the upper mantle but at 350 km depth its crystal structure starts to break down The composition remains but it takes a new and more compact form It is not technically olivine anymore because minerals have a definite crystal structure Olivine is not just an igneous mineral

So for example all the CO 2 produced by burning a litre of oil can be absorbed by less than 1 L of Olivine The end products of the reaction are silicon dioxide magnesium carbonate and small amounts of iron oxide Furthermore the process is exothermic which means that as a side effect heat is produced which can be used to generate electricity
