Kyanite Mineral | Uses and Properties - Geology.com
Kyanite's typical habit is a bladed crystal, although it sometimes occurs as radiating masses of crystals. Kyanite is often associated with other metamorphic minerals such as garnet, staurolite, and corundum.

Kyanite - Clark Science Center
Kyanite is usually found in metamorphic rocks such as pelitic schists and gneisses. Infrequently found in kimberlite, granitic pegmatite, and eclogite. Associated minerals include staurolite, garnet, sillimanite, and andalusite.
Kyanite - Wikipedia
Kyanite is a typically blue aluminosilicate mineral, found in aluminium-rich metamorphic pegmatites and sedimentary rock. It is the high pressure polymorph of andalusite and sillimanite , and the presence of kyanite in metamorphic rocks generally indicates metamorphism deep in …
Kyanite - University of North Dakota
Kyanite is a metamorphic mineral found in medium or high pressure mica schists and gneisses. Its formula is Al 2 SiO 5. Keys to identification are high relief, bladed habit, good cleavage and first order interference colors.
Kyanite: Properties, Occurrence, Uses – Geology In
Habits and Forms: Kyanite typically occurs as long, bladed crystals. It may also be found in fibrous or compact aggregates. Density: The density of kyanite ranges from 3.53 to 3.70 g/cm³. Specific Gravity: The specific gravity of kyanite ranges from 3.6 to 3.7. Solubility: Kyanite is generally insoluble in common acids and bases.

2009年6月1日 · Kyanite is a metamorphic mineral that occours in schists, gneisses and granite pegamatites. Associated minerals are quartz, feldspar, mica, garnet, corundum and staurolite. Kyanite occurs as bladed and tabular triclinic crystals.
Kyanite : Properties, Formation, Localities » Geology Science
2023年10月25日 · Kyanite is a mineral composed of aluminum silicate, and it belongs to the family of aluminosilicate minerals. Its chemical formula is Al2SiO5. Kyanite typically forms bladed crystals, and its name is derived from the Greek word “kuanos,” meaning blue, which reflects its most common blue coloration.

If it’s blue and bladed, it’s kyanite. Sometimes also if it’s white and bladed, or gray and bladed. Kyanite is a polymorph of andalusite and sillimanite. These three minerals share the same formula, but are stable at different P/T conditions.
