Amphiboles 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 chain of tetrahedra (as opposed to the single chain structure of pyroxene).

Systematic and well-planned synthesis of amphiboles, combined with careful spectroscopy, has greatly furthered our understanding of cation and anion order in amphiboles. The use of bond-valence theory to predict patterns of SRO

2020年2月10日 Amphiboles occur in both metamorphic and igneous rocks, frequently as dark elongated grains and crystals embedded in the rock, but can occasionally form well developed crystals. Such crystals are most commonly

Occurrence: Amphiboles have a wide range of chemical substitutions. Their chemical composition and general characteristics are very similar to the pyroxene group. They are an important constituent in a variety of plutonic and volcanic

2007年5月1日 The local occurrence of amphiboles favors a local infiltration of fluids at a late stage of the development of whole Horoman Complex rather than a pervasive fluid flow

Amphiboles convert easily at higher temperatures to pyroxenes. They are useful indicators of pressure-temperature conditions of formation—e.g., glaucophanes indicate relatively high

Amphiboles are important and essential minerals in many kinds of igneous rocks. For example, hornblende is widespread. It is common in granitic rocks but is even more common in rocks of intermediate to mafic composition.

2021年3月18日 Introduction. Asbestos is a general term that collectively refers to six mineral species: chrysotile and five fibrous amphiboles of commercial interest 1 – 3.The family of amphibole asbestos includes: amosite (fibrous variety of grunerite), crocidolite (fibrous variety of riebeckite), fibrous actinolite, fibrous anthophyllite and fibrous tremolite 1 – 3.

2023年4月23日 Chromite Uses Area. The only ore of chromium. Chromium is used with various other metals to give hardness to steel, also as a plating material because of its non-corrosive nature. Chromite bricks are used to a considerable extent as linings for metallurgical furnaces, because of their neutral and refractory character.

Description. Over 25 years ago, Volume 9 of Reviews in Mineralogy: Amphiboles and Other Hydrous Pyriboles seemed to contain all that was possible to know about this group of fascinating minerals.The subsequent twenty-five years have shown that this assessment was wrong: Nature was keeping a lot in reserve, and has since revealed considerable new complexity in the

The term amphibole, derived from the Greek amphibolos meaning “ambiguous,” was first used by Haüy in 1801. The complex nature of amphibole compositions is easily appreciated when it is remembered that all the eight elements that, together, make up 98% of the earth's crust, are present in common amphiboles.As a result of this range of composition, the group has a
