What is the difference between actinolite and tremolite?
Tremolite and Actinolite are two very similar minerals that form a series with each other and essentially share the same chemical formula. Tremolite has a greater presence of magnesium over iron, whereas Actinolite has a greater presence of iron over magnesium.
What is tremolite geology?
Tremolite is a member of the amphibole group of silicate minerals with composition: Ca2(Mg5.0-4.5Fe2+0.0-0.5)Si8O22(OH)2. Tremolite forms by metamorphism of sediments rich in dolomite and quartz. Tremolite forms a series with actinolite and ferro-actinolite.
What Colour is tremolite?
Tremolite is an important rock-forming mineral and occurs most commonly as a white to light green, granular to fibrous component of metamorphosed carbonate rocks, especially skarns and dolomite marbles, where the crystals and aggregates can become quite large.
Is tremolite rare or common?
Tremolite Information. White, colorless, gray, pale greenish, pink, brown. Small colorless and transparent tremolite crystals are very rare, and cut gems are true collector items.
What is tremolite used for?
Tremolite ranges in color from a milky white to a dark green and is found in other minerals such as talc and vermiculite. Tremolite was previously used in a variety of products such as paint, sealants, insulation, roofing and plumbing materials.
Is tremolite toxic?
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.
Is Jade a tremolite?
Tremolite jades with a low content of impurities are termed white jades. They typically are white or nearly so and generally are the most valuable jades.
What is another name for Hypersthene?
“Hypersthene” is not a commonly used term these days, often categorized instead as enstatite or ferrosilite.
What does Hypersthene meaning?
Hypersthene is a common rock-forming inosilicate mineral belonging to the group of orthorhombic pyroxenes. Its chemical formula is (Mg,Fe)SiO 3. It is found in igneous and some metamorphic rocks as well as in stony and iron meteorites.
