amphibolite wikipedia - EAS
- Amphibolite is a grouping of rocks composed mainly of amphibole and plagioclase, with little or no quartz. It is typically dark-colored and dense, with a weakly foliated or schistose (flaky) structure. The small flakes of black and white in the rock often give it a salt-and-pepper appearance.en.wikipedia.org/wiki/Amphibolite

https://fr.wikipedia.org/wiki/AmphiboliteUne amphibolite est une roche métamorphique contenant des amphiboles et des plagioclases caractéristique du métamorphisme général (mésozone à catazone). Possédant un clivage médiocre, elle a une texture grenue, pouvant aussi bien être aplitique que pegmatitique.

Amphibole - Wikipedia
https://en.wikipedia.org/wiki/AmphiboleXem thêm trên en.wikipedia.orgAmphiboles crystallize into two crystal systems, monoclinic and orthorhombic. In chemical composition and general characteristics they are similar to the pyroxenes. The chief differences from pyroxenes are that (i) amphiboles contain essential hydroxyl (OH) or halogen (F, Cl) and (ii) the basic structure is a double c…- Thời gian đọc ước tính: 8 phút

Metamorphic facies - Wikipedia
https://en.wikipedia.org/wiki/Metamorphic_faciesUnderlying principles. The different metamorphic facies are defined by the mineralogical composition of a rock. When the temperature or pressure in a rock body change, the rock can cross into a different facies and some minerals become stable while others become unstable or metastable. Whether minerals really react depends on the reaction ...
Amphibole — Wikipédia
https://fr.wikipedia.org/wiki/Amphibolemodifier. Les amphiboles sont une famille de minéraux, silicates de fer, de calcium ou de magnésium. Elles cristallisent dans les systèmes orthorhombique et monoclinique en prismes très allongés, avec un clivage typique selon les faces du prisme. Elles appartiennent au groupe des inosilicates .
Hornblende - Wikipedia
https://en.wikipedia.org/wiki/HornblendeHornblende. Hornblende is a complex inosilicate series of minerals. It is not a recognized mineral in its own right, but the name is used as a general or field term, to refer to a dark amphibole. Hornblende minerals are common in igneous and metamorphic rocks . The general formula is (Ca,Na)2-3(Mg,Fe,Al)5(Al,Si)8O22(OH,F)2.
