Serpentinite - Wikipedia

Serpentinite is a rock composed of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. Minerals in this group, which are rich in magnesium and water, light to dark green, greasy looking and slippery feeling, are formed by serpentinization, a hydration and metamorphic transformation of ultramafic rock from ...

Olivine is actually a mineral series, not a single mineral. In a mineral series two or more elements can substitute for one another without changing the crystal structure. In olivine, iron (Fe) and magnesium (Mg) do this, so the Olivine Series has two end members. Favalite is the iron-rich version, while forsterite is 在esci.umn.edu上查看更多信息

University of Minnesota’s Mineral Pages: Olivine

Serpentine is a name given to both a mineral and a rock, so don’t be confused by its dual use. The mineral serpentine commonly forms from the alteration of the olivine minerals, as water is incorporated into the minerals’ crystal structure. The rock serpentine forms from the metamorphism of olivine-rich ultramafic igneous rocks.

Serpentinite: Mineral information, data and localities.

A rock composed of one or more serpentine group minerals, e.g., antigorite, chrysotile and lizardite, formed by serpentinization (hydration and metamorphic transformation) of rock consisting almost wholly of ferromagnesian silicate minerals, such as olivine and pyroxene (usually ultramafic igneous rocks). Accessory chlorite, talc, and magnetite may be present.

Olivine Encyclopedia

Olivine is readily altered to the mineral serpentine by the hydration of its crystal structure by hot (400 – 800 ° C) water. This process occurs along mid-ocean ridges and other places where mafic rock is exposed to superheated water. Peridot (pronounced PER-ih-do) is a transparent variety of olivine

Carbon Sequestration via Mineral Carbonation: Overview

olivine. Olivine dissolves much more readily, so pre-treatment may not be necessary. However, olivine is not nearly as abundant as serpentine by about an order of magnitude. Another suggestion has been to go back to using acid to dissolve the minerals, but use a milder acid (e.g., acetic acid) as opposed to HCl.

Olivine: A rock-forming mineral. Used as the gemstone peridot.

Olivine in basalt: Lherzolite (a variety of peridotite) nodules in a xenolith collected from a basalt flow at Peridot Mesa, Arizona. These xenoliths often contain crystals of olivine with a color and clarity that is suitable for use as a peridot gemstone. This specimen is approximately 3 inches (7.6 centimeters) across.

Serpentine Gem5

Serpentine is mainly used for the carved figurines or decorated vases typical of Chinese art, most of them about 12 inches high. It is less tenacious than jade, but durable enough to be suitable material for the sculpting of classic vases with distinctive hanging chains carved from a single piece of stone.
