Kyanite, andalusite, and sillimanite are naturally occurring anhydrous aluminum silicate minerals. Each has the same chemical formula, Al 2 SiO 5, but differing crystal structures, making them …

The Al2SiO5 group of nesosilicates can be found in medium- to high-grade metamorphic rocks rich in aluminum. The group consists of three polymorphs: kyanite, sillimanite, and andalusite.

2023年8月25日 · Definition: Andalusite is a naturally occurring aluminum silicate mineral with the chemical formula Al2SiO5. It crystallizes in the orthorhombic crystal system, forming prismatic …

This is a book exclusively devoted to three minerals: the Al 2 SiO 5 polymorphs - andalusite, sillimanite, and kyanite. This may seem to be narrowly focused and esoteric. However, as …
