The Mineral Tremolite

Tremolite, a silicate mineral member belongs to the group amphibole with a composition: ☐Ca2 (Mg5. 0-4.5Fe2+0.0-0.5) Si8O22 (OH) 2. Tremolite forms by metamorphism of Sediments that are rich in dolomite and quartz form the mineral Tremolite, which uses ferro-actinolite and actinolite in the process. Magnesium tremolite in its pure form has a creamy white color, but with increasing iron content, you can see it in shades of dark green. Nephrite, that is one among the 2 minerals of jade, is a green variety of green tremolite.
Chemical Formula
Ca2 (Mg5. 0-4.5Fe2+0.0-0.5) Si8O22 (OH) 2
Derivation of Name
Johann Georg Albrecht Höpfner in 1979 named it Tremolite because it was found in the Tremola Valley in Switzerland, which is supposed to be the origin of this mineral as described by the dealer who gave him the specimens. They called this mineral as Sternspath and Säulenspath.

Tremolite is an indicator of temperature, because it converts to Diopside temperatures that are high
Tremolite results from contact metamorphism of magnesium and calcium and rich sedimentary siliceous rocks, besides metamorphic rocks with greenschist facies (Wiki Description- a body of rock with specified characteristics) that derive from rocks that bear magnesium carbonate or ultramafic rocks. Associated minerals include Calcite, Dolomite, Grossular, Wollastonite, Talc, Diopside, Forsterite, Cummingtonite, Riebeckite and Winchite

Tremolite is among the highest vibrating crystals, and resonates with a powerful energy. Its energy is felt within the highest chakras... and is particularly noticeable at both the third eye and crown chakra. Its energy is known to help you to open new pathways in the brain, allowing you to access the morphic field of knowledge.

You can see their notable Occurrences in Wilberforcein in Ontario, Canada; and in the United States of America in Canaan, New York, Arizona, California, and Connecticut; and Piemonte and Tyrol in Italy; Switzerland’s Tremola Valley, Finland and Tanzania.

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. Asbestosis is a lung disease caused by inhalation of asbestos particles, which causes several cancers, particularly lung cancer and mesothelioma.

Color is usually white or gray but can be greenish, colorless, yellow and violet.
