- Andalusite - Wikipedia
Andalusite is a common metamorphic mineral which forms under low pressure and low to high temperatures The minerals kyanite and sillimanite are polymorphs of andalusite, each occurring under different temperature-pressure regimes and are therefore rarely found together in the same rock
- Andalusite: Mineral information, data and localities.
Andalusite was first analysed by Werner on specimens coming from Spain Both Werner and Delamétherie believed that the specimens came from Andalusia, which is why the latter named it "andalusite"
- What is Andalusite? What is Chiastolite? - Geology. com
Andalusite is an aluminosilicate mineral with a chemical composition of Al 2 SiO 5 It forms at low to medium metamorphic temperatures and pressures where argillaceous rocks (such as shale) are exposed to regional and contact metamorphism
- Andalusite | Properties, Formation, Occurrence and Uses
Definition: Andalusite is a naturally occurring aluminum silicate mineral with the chemical formula Al2SiO5 It crystallizes in the orthorhombic crystal system, forming prismatic crystals that often display a distinctive cross-shaped pattern when viewed in cross-section
- What Is Andalusite? Mineral, Gem, and Industrial Uses
Andalusite is an aluminum silicate mineral valued as a gemstone and industrial material, known for its pleochroism and heat-resistant properties
- Andalusite – Mineral Properties, Photos and Occurrence
Andalusite is a typical mineral of aluminum rich rocks, where it forms under low pressure and low to high temperature conditions Source rocks are typically represented by various schists or some granites and pegmatites
- Andalusite - Gems Minerals
Andalusite is a well-known aluminum silicate mineral that plays a central role in metamorphic geology It is one of the three primary polymorphs of Al₂SiO₅, alongside kyanite and sillimanite
- Andalusite | Metamorphic, Heat-Resistant, Silicate | Britannica
Andalusite, (Al2SiO5), aluminum silicate mineral that occurs in relatively small amounts in various metamorphic rocks, particularly in altered sediments It is found in commercial quantities in the Inyo Mountains, Mono county, Calif , in the United States; in Kazakhstan; and in South Africa
