Definition of tremolite in US English:



  • A white to gray amphibole mineral that is characteristic of metamorphosed dolomitic limestones.

    • ‘The presence of several amphibole minerals, such as tremolite, actinolite, anthophyllite, was confirmed.’
    • ‘No ad hoc studies on the incidence of mesothelioma in areas of Italy characterized by the presence of tremolite in soil are available.’
    • ‘Although this could be the result of a lower biopersistence of chrysotile compared with amphiboles, the environmental survey confirms that tremolite is the main type of asbestos involved.’
    • ‘Size characteristics for tremolite and chrysotile fibers are reported in Table 7.’
    • ‘Amosite, fibrous anthophyllite, fibrous tremolite, fibrous actinolite, and crocidolite are amphiboles, double-chain silicates, which observed microscopically look like sharp needles.’
