Examples of amphibole
amphibole
Other solid deposits include halite, amphibole, cryolite, soda niter, and zeolite.
From the en.wikipedia.org
The andesite rock contains some visible crystals of pyroxene or amphibole.
From the en.wikipedia.org
Actual surface amphibole deposits in residential areas were ignored for testing purposes.
From the en.wikipedia.org
Amosite, crocidolite, tremolite, anthophyllite and actinolite are members of the amphibole class.
From the en.wikipedia.org
Pseudomorphs of amphibole after pyroxene are known as uralite.
From the en.wikipedia.org
Pargasite is a rare magnesium-rich amphibole with essential sodium, usually found in ultramafic rocks.
From the en.wikipedia.org
Amphibole class fibers are needle-like.
From the en.wikipedia.org
Amphibolite is a grouping of rocks composed mainly of amphibole and plagioclase feldspars, with little or no quartz.
From the en.wikipedia.org
The mafic mineral in Proterozoic anorthosite may be clinopyroxene, orthopyroxene, olivine, or, more rarely, amphibole.

- A mineral or mineral variety belonging to the amphibole group
- Amphibole defines an important group of generally dark-colored rock-forming inosilicate minerals, composed of double chain SiO4 tetrahedra, linked at the vertices and generally containing ions of iron and/or magnesium in their structures.
- A subgroup of asbestos characterized by crystals forming in a chain-like structure.
- A complex family of silicate minerals with similar physical features and a general formula A0-1 X2Y5 (Si,Al)8O22(OH,F,CL)2 where A= Ca, Na, K; X = Ca, Fe, Mg, Mn, Na; Y = Al, Fe, Mg, Mn, Ti. Amphiboles form in both igneous and metamorphic environments. See hornblende.
- An important rock-forming mineral group of ferromagnesian silicates. Amphibole crystals are constructed from double chains of silicon-oxygen tetrahedra.
- A common rock-forming silicate; a chain silicate mineral that contains a double chain structure. Amphibole is often dark in color and is #6 on the Mohs scale of hardness. It has a variable chemical composition of calcium, iron, magnesium, silicon, oxygen, and many others.
- N. - rock-forming silicate similar to asbestos and hornblende.
- A common mineral composed of silicate of magnesium and calcium, (with usually aluminum and iron), which occurs in monoclinic crystals and comes in many varieties, each varying in color and in composition. The color varies from white to gray, green, brown, and black. Jade is a form of Amphibole.
