What kind of mineral is tremolite?
silicate minerals
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.
Where is actinolite found in the world?
Major sources for these forms of actinolite are Taiwan and Canada. Other sources are Madagascar, Tanzania, and the United States.
What rock is tremolite found in?
Tremolite is most frequently found in impure, crystalline, dolomitic limestones where it has formed on the recrystallization of the rock during metamorphism. It is also found in talc schists.
What does actinolite mean?
Actinolite is a monoclinic mineral, and occurs in long, slender, green needlelike crystals, or in fibrous, radiated forms in metamorphic rocks. Chemical formula: Ca2(Mg,Fe)5Si8O22OH2. 1. (mineralogy) A mineral with monoclinic crystals of the chemical formula Ca2(Mg,Fe)5Si8O22(OH)2, belonging to the amphibole group.
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 rare or common?
rare
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.
Is actinolite toxic?
Exposure to the PEL every day over a 45-year working lifetime has been estimated to be associated with an increased risk of cancer (lung, mesothelioma, and gastrointestinal) of 336 cases per 100,000 exposed persons and an increased risk of asbestosis of 250 cases per 100,000 exposed persons.
Is actinolite rare or common?
Actinolite is a fairly common crystal that has localities all over the world. Countries such as Brazil, Russia, Canada, China, and the USA all have an abundance of this mineral below them! Actinolite has 2 very rare forms that are highly desired by collectors and practitioners.
What happens if you breathe in asbestos once?
Once lodged in the lung tissue, these fibers can cause several serious diseases, including lung cancer, asbestosis (a scarring of the lung tissue) and mesothelioma (cancer of the lining of the lung cavity).
What are the 4 major asbestos related diseases?
There are 4 main diseases caused by asbestos exposure:
- Pleural disease. Pleural plaques and pleural thickening are non-cancerous conditions affecting the outer lining of the lungs (the pleura).
- Mesothelioma.
- Asbestosis.
- Lung cancer.
How do you clean tremolite?
You can also use a handheld water gun (gently and from far distance first), a steam cleaner and an ultrasonic bath. Chemically, actinolite/tremolithe is quite stable, so you can even use strong muriatic acid (>20%) to remove iron stainings or to loosen dirt if no other sensible minerals to protect.
Is jade a tremolite?
Hexagonite is the rarest of the gem varieties of tremolite. If tremolite occurs in very tiny fibrous crystals, densely matted and interlocked, it is then known as nephrite (jade).
Is actinolite a form of asbestos?
Asbestos is a group of six naturally occurring silicate minerals. The types of asbestos include chrysotile, amosite, crocidolite, anthophyllite, tremolite and actinolite. Asbestos types are categorized into two families: serpentine and amphibole, which indicate their fiber shape.
What is the value of actinolite?
1.63); when chatoyant material is cut, it exhibits a fine eye. Actinolite is easy to cleave and hard to cut and would make a poor jewelry stone. Actinolite is the chief constituent of nephrite (jade). Smaragdite is a chrome-rich tremolite from Tanzania.

Do N95 masks protect against asbestos?
A: An N95 mask is a disposable filtering facepiece respirator with two straps. When worn properly (with the mask making a tight seal with the user’s face), it can protect against hazardous airborne particles. N95 masks do not protect against gases, vapors and cannot be used for asbestos, and they do not provide oxygen.
What are the first signs of asbestos exposure?
Asbestosis signs and symptoms may include:
- Shortness of breath.
- A persistent, dry cough.
- Chest tightness or pain.
- Dry and crackling sounds in your lungs when you inhale.
- Fingertips and toes that appear wider and rounder than usual (clubbing)
What are the first signs of asbestosis?
Symptoms of asbestosis
- shortness of breath.
- persistent cough.
- wheezing.
- extreme tiredness (fatigue)
- pain in your chest or shoulder.
- in more advanced cases, clubbed (swollen) fingertips.
What part of the body does asbestos affect?
The asbestos fibers irritate and scar lung tissue, causing the lungs to become stiff. This makes it difficult to breathe. As asbestosis progresses, more and more lung tissue becomes scarred. Eventually, your lung tissue becomes so stiff that it can’t contract and expand normally.
What will dissolve calcite?

Is tremolite a Pleochroic?
Color – Tremolite is clear to light green, may be slightly pleochroic. The color and pleochroism are more pronounced with greater Fe content. Cleavage – Tremolite shows typcial amphibole cleavage. One cleavage in longitudinal sections, and two creating a 60o-120o cleavage angle when viewed in end section.
What is name a precious gem?
Traditionally, precious stones were the Big Four gemstones — diamonds, emeralds, rubies, and sapphires.
Can you wash asbestos out of clothes?
You cannot easily wash asbestos out of clothes. Trying to do so can expose you to asbestos. Regular washing machines are not designed to clean asbestos-contaminated clothing. Trying to wash contaminated clothing will cause asbestos fibers to become airborne.
How long does it take for asbestos to affect you?
The effects of long-term exposure to asbestos typically don’t show up until 10-40 years after initial exposure. Symptoms can vary in severity. Asbestosis signs and symptoms may include: Shortness of breath.
Can your lungs heal from asbestos?
There’s no cure for asbestosis once it has developed, as it’s not possible to reverse the damage to the lungs. But some treatments can help, such as: pulmonary rehabilitation – a programme of exercises and education to help manage your symptoms.
