Why Amphibole Is Important?

Amphiboles also are important constituents in a variety of plutonic and volcanic igneous rocks that range in composition from granitic to gabbroic. ... The combination of prismatic form and two diamond-shaped directions of cleavage at about 56° and 124° is the diagnostic feature of most members of the amphibole group.

What is the importance of amphibole?

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.

Why amphibole is considered as mineral?

Amphiboles are minerals of either igneous or metamorphic origin. Amphiboles are more common in intermediate to felsic igneous rocks than in mafic igneous rocks, because the higher silica and dissolved water content of the more evolved magmas favors formation of amphiboles rather than pyroxenes.
