Natural Fibres by J Gordon Cook
Actinolite is an iron calcium magnesium silicate which occurs as greenish masses of fibrous crystals. (3) Crocidolite (Blue Asbestos; Amosite) is a iron sodium silicate which occurs as long flexible fibres of bluish colour, and with a characteristic silky lustre. The fibres are 7.5–10cm (3–4 in). Crocidolite has a higher tensile strength than other asbestos fibres, but is not so resistant to high temperatures as crysotile.

Actinolite is an important member of the monoclinic series, forming radiating groups of acicular crystals of a bright green or greyishgreen colour. It occurs frequently as a constituent of crystalline schists. The name (from aktis, a ray, and lithos, a stone) is a translation of the old German word Strahlstein, radiated stone. Glaucophane, crocidolite, riebeckite and arfvedsonite form a somewhat special group of alkaliamphiboles. The two former are blue fibrous minerals occurring in crystalline ...

77Mg Actinolite is the characteristic mineral in low- grade metamorphic rocks of the Nakoso district, Japan (Shido 1958), and the actinolite-epidote-chlorite assemblage is common in the schists of basic composition. The amphibole is often sharply zoned and consists of a pale green or colourless actinolite with a well defined blue-green hornblende margin. The two amphiboles ...

ACTINOLITE. The term for a calcium-iron-magnesium amphibole, the formula being Ca2(Mg,Fe)SSigO22(OH)2 but the amount of iron varies considerably. It occurs as bladed crystals or in fibrous or granular masses. Its hardness is 5–6, sp gr 3–3.2, color green to grayish green, transparent to opaque, luster vitreous to silky or waxy. Iron in the ferrous state is believed to be the cause of its green color . Actinolite derives its name from the frequent radiated groups of crystals. Essentially it ...

- Actinolite amphibole (California, USA)
Actinolite from California, USA.
A mineral is a naturally-occurring, solid, inorganic, crystalline substance having a fairly definite chemical composition and having fairly definite physical properties. At its simplest, a mineral is a naturally-occurring solid chemical. Currently, there are over 5100 named and described minerals - about 200 of them are common and about 20 of them are very common. Mineral classification is based on anion chemistry. Major categories of minerals are: elements, sulfides, oxides, halides, carbonates, sulfates, phosphates, and silicates.
The silicates are the most abundant and chemically complex group of minerals. All silicates have silica as the basis for their chemistry. "Silica" refers to SiO2 chemistry. The fundamental molecular unit of silica is one small silicon atom surrounded by four large oxygen atoms in the shape of a triangular pyramid - this is the silica tetrahedron - SiO4. Each oxygen atom is shared by two silicon atoms, so only half of the four oxygens "belong" to each silicon. The resulting formula for silica is thus SiO2, not SiO4.
Amphibole is a group of silicate minerals. The garden-variety type of amphibole is hornblende. Other common varieties include tremolite and actinolite. The sample shown above is actinolite, a greenish-colored amphibole having the formula Ca2(Mg,Fe)5Si8O22(OH)2 - calcium magnesium iron hydroxysilicate. Actinolite forms a continuous chemical spectrum with whitish-colored tremolite. Unlike tremolite (see elsewhere in this photo album), actinolite has a significant iron component, which causes the dark coloration. Actinolite often forms radiating clusters of elongated blades.

- Log Drive On Skootamatta River Near Actinolite
This photo and information contributed by the Community Archives of Belleville and Hastings County show a log driver with his pike pole being watched by three young boys from what appears to be a logging trail with six others seated on the ground nearby.
Logging has been an important industry in Hastings County from its early settlement to the 21st century. Before mechanized equipment came into use, logs were felled in the winter and hauled to the riverbank to await the spring thaw. The logs were driven down the river to the sawmill when the water level was high after the spring melt.
The Skootamatta River carried logs to Billa Flint's water powered sawmill at Actinolite (then named Troy), or further on to the Moira River for the longer journey down to the large mills in Belleville.
