amphibole | mineral | Britannica

The term biopyribole has been used to describe any mineral that has both I beams and sheetlike structures. The name comes from biotite (mica), pyroxene, and amphibole. Biopyriboles have chain widths and repeat sequences like pyroxenes (single-chain repeats), amphiboles (double-chain repeats), and triple-chain repeats.

Amphibole Asbestos - an overview | ScienceDirect Topics

Asbestos minerals are divided into two major categories: serpentine and amphibole asbestos.The fibrous-asbestiform variety of serpentine is called chrysotile. Chrysotile and amphibole asbestos are both silicates sharing fibrous-asbestiform crystal habits but holding very different structural units at a molecular scale (Whittaker, 1956; Yada, 1971; Bailey, 1988; Devouard and Barronet, 1995).

What is the Protolith of amphibolite? - FindAnyAnswer.com

Amphibolite is a metamorphosed mafic igneous rock (basalt, gabbro) although it is usually difficult to determine the protolith because original features are often obliterated. Basalt is composed of pyroxene + plagioclase. However, the term "para-amphibolite" is outdated and generally not used anymore.

Amphibolite is used for exterior building stones, facing stones, curbing, and paving stone. Amphibolite is used for interior countertops, entryways, floor tiles, and in hotels and kitchens. When the presence of hydroxyl groups is found in the structure of amphiboles, it decreases their thermal stability relative to the more refractory (heat ...

Quick Answer: What Color Is Amphibolite Rock ...

What is amphibolite rock used for? It is used as paving stones and as a veneer or facing on buildings (both for interior and exterior use). It is also used as crushed stone for the usual crushed stone applications such as road and railroad bed construction. In this application it is used locally, near the source of the amphibolite.

A rare Phanerozoic amphibolite-hosted gold deposit at ...

The Danba gold deposit is located in a poorly-documented gold province on the north-western margin of the Yangtze Craton. It is sited in Devonian sequences in a high-grade metamorphic terrane that includes an extensional metamorphic core complex. Around the deposit, peak metamorphic conditions of 6 ± 0.5 kbar and 650 ± 50 °C at ca. 193 Ma were followed by retrograde sillimanite-grade ...

epidote-amphibolite facies | geology | Britannica

epidote-amphibolite facies, one of the major divisions of the mineral-facies classification of metamorphic rocks, the rocks of which form under moderate temperature and pressure conditions (250°–400° C [500°–750° F] and up to 4 kilobars [1 kilobar equals about 15,000 pounds per square inch]).This facies grades into the greenschist facies under less intense metamorphic conditions and ...

It's measured in bars and ranges from 1 bar at sea level to around 10,000 bars at the base of the crust. For metamorphic rocks, pressures range from a relatively low-pressure of 3,000 bars around 5-6 kilometers below the Earth's surface to a relatively high pressure of 50,000 bars around 15-35 kilometers.
