Amphibole Group

Term: Amphibole GroupDefinition: A group of silicate minerals characterized by their elongated, fibrous crystal structure, which includes several types of asbestos.Phonetic Pronunciation: (AM-fih-bohl GROUP)Origin: The term "amphibole" is derived from the Greek words "amphis," meaning "both," and "bolē," meaning "throw," alluding to the mineral's variable properties and its ability to be mistaken for other minerals. This group of minerals has been identified and used since ancient times, with their fibrous nature noted for its utility.Significance in Asbestos Context: The Amphibole Group is significant in asbestos issues because it includes several types of asbestos fibers, such as amosite and crocidolite, which are known to be particularly hazardous when inhaled. Understanding the properties of these minerals is crucial for identifying asbestos-containing materials and assessing exposure risks.Example Sentence: "The presence of amphibole asbestos in the building materials was a major concern for the workers during the renovation project."Related Terms: Asbestos, Amosite, Crocidolite, Chrysotile, Serpentine GroupNotes: - Not all amphiboles are asbestos, but those that are can be highly dangerous. - Amphibole asbestos fibers are generally more resistant to chemical and thermal breakdown than chrysotile fibers. - The term 'amphibole' refers to a broader mineral group, not exclusively asbestos.
