Historically, asbestos was mainly used for insulating buildings and homes against cold weather and noise. . With respect to other fibrous tremolites of the Western Alps, it shows a small reduction offibrousness and a consistent increase of the surface area under grinding. The definition of how much iron must be present before tremolite becomes actinolite is not universally recognized and has changed over time (Wylie and Verkouteren 2000). One of these, namely chrysotile, belongs to the serpentine family of minerals, while all of the others belong to the amphibole family. Tremolite forms by metamorphism of sediments rich in dolomite and quartz, and occurs in two distinct forms, crystals and fibers. Exposure to Tremolite is a calcic amphibole and the magnesian end-member of the tremolite – ferro-actinolite series, a continuous solid solution dictated by the substitution of Mg by Fe 2+. Tremolite fibers in these samples were described as generally fine, straight, and needle-like with diameters around 0.
