This mineral is alternatively known as Gilstein, and along with kaolin and alumina, this mineral is used to synthesize cordierite.
This mineral is alternatively known as Gilstein, and along with kaolin and alumina, this mineral is used to synthesize cordierite. It is often found along with chlorite and magnesium carbonate, and their mafic and ultramafic origin involves the addition of carbon dioxide to serpentine. Carbonates off this mineral can be formed during the metamorphism of magnesium-rich minerals such as olivine in a process known as steatization. Like mica, it is classified as a layer silicate, and a common type of rock containing this mineral is grayish-green in color and slippery to the touch, giving it the name soapstone. For 10 points, identify this type of mineral that is a major component of baby powder and has a Mohs hardness of only one.
