Where are tremolite found?
Where is Tremolite Found? Outside of the United States, tremolite was primarily mined in South Africa and India. In South Africa, it was extensively mined in the beginning of the 20th century, but it became secondary to the mining of amosite and crocidolite.
Can you get mesothelioma from one exposure?
This type of cancer is almost exclusively caused by exposure to asbestos. A long exposure can cause mesothelioma and so can short ones, as each exposure is cumulative.
How big are the fibers of tremolite asbestos?
Tremolite and actinolite both form thin, parallel, flexible fibers up to 10 in (25 cm) in length, which are used commercially as asbestos. Tremolite is known as nephrite jade when it is massive and fine-grained. The mineral is abundant and widespread.
What are the extinction characteristics of three fibrous tremolites?
The three fibrous tremolites have dif ferent fiber widths and, as such, exhibit different ex tinction characteristics. The smaller the diameter of the fibers, the greater number of particles exhibiting parallel extinction. The sample with the smallest widths (< 0.5 µm) displayed parallel extinction for all
What are the physical properties of tremolite crystals?
Crystallography: Monoclinic; prismatic. Crystals prismatic in habit; the prism faces make angles of 56° and 124° with each other. The termination of the crystals is almost always formed by the two faces of a low clinodome (Figs. 400 and 401). Tremolite is often bladed and frequently in radiating columnar aggregates.
Where can you find tremolite in a rock?
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. Actinolite commonly occurs in the crystalline schists, being often the chief constituent of green-colored schists and greenstones.
