게시 ~에 의해 Kingjy

Actinolite is a chain-like silicate mineral of magnesium, iron, calcium, sodium and aluminum containing hydrogen and oxygen. It is a kind of minerals in the hornblende group and has a similar relationship with Tremolite. . It has two variants. One is that actinolite and tremolite form a cryptocrystalline, tough and dense mass called nephrite; the other is that actinolite and tremolite form fibrous aggregates and are easily split into filaments, called angles. Amphibolite asbestos (Amphibolite) actinolite belongs to the monoclinic crystal system, the crystals are columnar needles, usually shot or fibrous aggregates, with glass luster, transparent to translucent, and hardness of 5.5-6.0. Its color is mainly green, and with the increase of iron content, it shows different degrees of green, including green, light green, blue-green, black-green and black. 동시에, it has obvious pleochroism, from yellow to dark green.

Actinolite is a common mineral. Larger crystals are rare. Only light green to dark green transparent crystals are considered, especially those with bright colors and high transparency. It can be used to make faceted gems, but because of its cleavage development It is fragile and difficult to process, so it is rare. It is mainly used for collection. For this reason, the precious gems of Actinolite are also rare. The Calgary Divo Group in Canada collects a green Yangqi that has been processed into a stepped shape. Stone gem, weighing 2.06 캐럿, produced in white Africa. In addition to being used for gemstones, actinolite is a gemstone that weighs 2.06 carats and is produced in Africa. In addition to the available gemstones, actinolite, its variant nephrite, can be used as a carving material; and amphibole asbestos has the characteristics of high temperature resistance, acid and alkali resistance, non-conductivity, and non-heat. It can be used in metallurgy and chemical industries. For heat preservation, heat insulation, edge and anti-corrosion materials. Gemstones similar to actinite include diopside, green tourmaline, 등., which can be distinguished according to their crystal shape, hardness, specific gravity, and refractive index.

Actinolite is produced in limestone, dolomite and regional metamorphic rocks that are in contact with metamorphism. It is often symbiotic with minerals such as albite, chlorite, epidote, talc and quartz. Actinolite is produced all over the world, and the high-quality, 순수한, dark green small crystals are mostly produced in Madagascar, which is the only place where the surfaced actinite is produced. Green and transparent crystals are also produced in Tanzania, and actinite crystals that look like golden emeralds have also been found in the United States and Taiwan Province of China.
