Where is Monticellite found?
Pure kirschsteinite is only found in synthetic systems. Monticellite is named after Teodoro Monticelli Italian mineralogist (1759–1845). Kirschsteinite is named after Egon Kirschstein, German geologist….Monticellite.

What is the chemical formula of forsterite?
Mg2SiO4
Forsterite is a magnesium silicate crystal with the chemical formula Mg2SiO4 derived from the olivine mineral group [1]. Olivine is a group of minerals composed of iron (Fe) and magnesium (Mg).
Where is wollastonite found?
Deposits of wollastonite have been found in Arizona, California, Idaho, Nevada, New Mexico, New York, and Utah. These deposits are typically skarns containing wollastonite as the major component and calcite, diopside, garnet, idocrase, and (or) quartz as minor components.
What is difference between forsterite and fayalite?
The other mineral is forsterite. Fayalite is the iron rich member with a pure formula of Fe2SiO4. Forsterite is the magnesium rich member with a pure formula of Mg2SiO4. The two minerals form a series where the iron and magnesium are substitutable for each other without much effect on the crystal structure.
Can fayalite be found on Earth?
The mineral, which is reddish brown to black in color, is mainly mined for use as a gemstone and is also used for sand blasting. Fayalite can be found worldwide in igneous rock and abyssal rocks.
How do you identify augite?
Augite is usually green, black, or brown in color with a translucent to opaque diaphaneity. It usually exhibits two distinct cleavage directions that intersect at slightly less than 90 degrees. A hand lens is often needed to properly observe the cleavage, especially in fine-grained rocks.
Where can you find augite on earth?
It also occurs in some metamorphic rocks formed at high temperatures (1,065°F/575°C or above). Augite is a common constituent of lunar basalts and some meteorites. Notable crystal localities are in Germany, the Czech Republic, Italy, Russia, Japan, Mexico, Canada, and USA.
Does wollastonite contain asbestos?
In the single instance in which a wollastonite producer initially did report an isolated/trace asbestos contamination, it is of particular importance to note that the mineral fiber in question turned out not be asbestos.
