2021-7-7 · Actinolite is an amphibole silicate mineral and is actually quite common in occurrence, although gem-quality materials are extremely rare. Actinolite belongs to a series of minerals ranging from iron-rich tremolite to magnesium-rich ferro-actinolite amphiboles.Mineral Database National Museum Wales,Introduction: actinolite is a member of the amphibole group. It forms a series with tremolite and ferro-actinolite being more iron-rich than the former. It occurs in basic rocks metamorphosed under low-grade metamorphic conditions (greenschist and blueschist facies).
The dissolution rates of the minerals actinolite and chlorite were determined from metabasalt element release rates measured at 25 °C and 2 < pH < 12 in mixed flow reactors. At pH 2.0 and 3.2, chlorite rates are 3 and 5 times faster, respectively, than corresponding actinolite rates, whereas the Si release rates from metabasalt are intermediate between chlorite and actinolite rates.Geochemistry, geochronology and mineralisation ,2013-3-23 · a diopside-actinolite-K-feldspar-bornite calc-potassic style alteration assemblage and associated vein stockwork. This quartz-free mineral assemblage is associated with high gold grades (2-8 g/t Au) and is typical of alteration assemblages found in quartz undersaturated alkaline porphyry systems.
Actinolite. Actinolite is pale green, green, greyish-green and sometimes dark green in colour, and occurs as fibrous, radial crystals (acicular) and massive to granular aggregates in the ground mass. The mineral is formed as a replacement of other minerals like pyroxenes. In many cases it is associated with chlorite, epidote, pyrite, and quartz.Mineralogical Characteristics of the Nickel Laterite,2019-11-8 · The concentrations of nickel and iron of the nickel laterite are 1.99 wt% and 17.55 wt%, respectively. The serpentine, olivine, clay, chlorite, hematite, and magnetite are the major minerals, and the pyroxene, actinolite, limonite, and chromite are the minor minerals in the nickel laterite in Southeast Sulawesi, Indonesia.

Actinolite. Actinolite is a member of a series that contains varying amounts of iron and magnesium. Tremolite is the Mg end, and ferroactinolite the Fe end, with actinolite in the middle. Actinolites with more than 50% Fe are very rare. Catseye actinolite exists (S.G. 3.0, R.I. 1.63); when chatoyant material is cut, it exhibits a fine eye.Hydrothermal Alteration : 8 important alteration ,Actinolite.
