Actinolite is a calcium magnesium iron silicate hydroxide mineral of the amphibole group. Actinolites from the Franklin orebody are invariably zincian and manganoan. However, the analyses of Klein and Ito (1968), together with many by [Dunn], strongly suggest that Fe, Mn, and Zn are limited in many Franklin actinolite samples and may be ordered.

Actinolite asbestos An example of the element Iron: Sample Image | Spin Video | QuickTimeVR Rotation; Actinolite asbestos. The name "asbestos" used to mean a wonder-material, an insulator without equal and a strengthening fiber so cheap and strong it was used in building materials worldwide. Today the name means nothing but death and ruin.

Asbestos comprises six naturally occurring substances: chrysotile (which belongs to the serpentine group of minerals), crocidolite, amosite, anthophyllite, tremolite and actinolite (all belonging to the amphibole group of minerals). Most of the world usage of asbestos has been chrysotile and much smaller amounts of crocidolite and amosite, whereas the other three amphiboles are important as contaminants of other minerals or agricultural soil.

The photo associated with this text is of Actinolite, one of the most potently carcinogenic forms of asbestos. Its sharp, needle-like fibers make it especially dangerous. The samples below represent all the major natural sources of asbestos fibers. Mineral details: Actinolite (variety "Byssolite"), amphibole group, double-chain silicate.

Actinolite is an intermediate member in a solid-solution series between magnesium-rich tremolite, Ca 2 (Mg 5.0-4.5 Fe 2+ 0.0-0.5)Si 8 O 22 (OH) 2, and iron-rich ferro-actinolite, ☐Ca 2 (Mg 2.5-0.0 Fe 2+ 2.5-5.0)Si 8 O 22 (OH) 2. Mg and Fe ions can be freely exchanged in the crystal structure. Like tremolite, asbestiform actinolite is regulated as asbestos. Occurrence

Actinolite and Tremolite both contain a form of asbestos which is made of movable and elastic fibers. Actinolite asbestos is less common; most forms are in fact Tremolite. This form of the mineral contains significant health hazards and should never be brought near the mouth. If its fibers or particles enter the lungs, they can cause asbestosis.

Actinolite and Tremolite both contain a form of asbestos which is made of movable and elastic fibers. Actinolite asbestos is less common; most forms are in fact Tremolite. This form of the mineral contains significant health hazards and is further discussed in the Tremolite mineral detail page.

The serpentine fiber, chrysotile, accounts for most of the commercially used asbestos, favored for its properties of heat resistance, flexibility, and ease of spinning for textiles. Five categories of amphiboles are recognized: crocidolite, amosite, anthophyllite, tremolite, and actinolite. These more rigid fibers are less commonly used but are still pathogenic.
