Actinolite is a mineral that is part of a so-called solid-solution series, which means that you get different but related minerals depending on the amounts of (in this case) iron and magnesium that are present.The magnesium-rich end member is tremolite; the iron-rich end member is ferro-actinolite; and what lies between is actinolite.. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. The name actinolite is derived from the Greek word aktis (ἀκτίς), meaning "beam" or "ray", because of the mineral's fibrous nature. 2. How does Actinolite asbestos affect the body? Actinolite has a greater presence of iron over magnesium, whereas Tremolite has a greater presence of magnesium over iron.

The name actinolite is derived from the Greek word aktis, meaning “beam” or “ray”, because of the mineral’s fibrous nature. A calcium magnesium silicate, tremolite forms a solid-solution series with ferroactinolite, where iron substitutes in increasing amounts for magnesium. 1. Jade-Wikipedia. Industrial chemicals are often present in powder form and therefore often contain much higher dangers than natural, crystalline substances. The name actinolite is derived from the Greek word aktis (ἀκτίς), meaning "beam" or "ray", because of the mineral's fibrous nature. Actinolite is a member of the amphibole class of asbestos minerals. Actinolite is an amphibole mineral.Tremolite and Actinolite are identical minerals; their chemical formulae are alike, with a combination of iron and magnesium. A mineral with monoclinic crystals of the chemical formula Ca 2/sub [sub]5 Si 8 O 22/sub [sub]2, belonging to the amphibole group. Uses. Actinolite is the intermediate member of the tremolite-ferro-actinolite series. Actinolite is an amphibole silicate mineral with the chemical formula. It is an amphibole silicate mineral, which belongs to the series of minerals known as Ferro-actinolite and tremolite. Chemical Formula: {Ca 2}{(Mg,Fe 2+) 5}(Si 8 O 22)(OH) 2 Locality: Common world wide. The mineral is named for Cymru, which is the Welsh word for Wales. It occurs from the conversion of dolomite, silica and water into tremolite, calcite and carbon dioxide by way of the following formula: . 2012), since it is entrenched in the literature. Actinolite-Tremolite Series. Actinolite. The iron content in the Actinolite mineral is more than that of magnesium whereas in Tremolite, the magnesium is more than iron. Actinolite is an amphibole silicate mineral with the chemical formula Ca2(Mg,Fe)5Si8O22(OH)2. The middle member of this series with an intermediate composition is called actinolite (the silky fibrous mineral form is one form of asbestos). The name actinolite is derived from the Greek word aktis (ἀκτίς), meaning "beam" or "ray", because of the mineral's fibrous nature.
