Synonyms
asbestiform tremolite, tremolitic asbestos
Examples of usage
- Tremolite can be a contaminant in some asbestos deposits.
- Geologists often study tremolite to understand metamorphic processes.
- The presence of tremolite in a rock can indicate specific geological conditions.
- Tremolite is sometimes used in the production of heat-resistant materials.
Etymology
The term 'tremolite' is derived from its historical name, which is linked to its discovery in the Tremola Valley, Switzerland. The suffix '-ite' is commonly used in mineralogy to denote minerals. The name was first applied to the mineral in the early 19th century, when mineral classification became more rigorous. Tremolite is a member of the amphibole group, which has a complex structure involving chains of silica tetrahedra bonded by cations such as magnesium and iron. Over time, its association with asbestos fibres has led to health concerns, and tremolite is now often mentioned in discussions about mineral safety and environmental health.
