Differences Between Pyroxene and Amphibole Difference

Differences Between Pyroxene and Amphibole. These two crystals are known as dark crystals because the light defines the formations of these crystals. Indeed, the light has a great impact on how these minerals are created. Thus, amphiboles are a group of crystals that can be yellow, transparent, white, blue or brown. It composes of inosilicate forms.

Pyroxene Group. The pyroxene group is composed of minerals of the general formula XYSi2O6, where X and Y are two divalent cations or a monovalent and a trivalent cation. If X and Y are the same small radius divalent cation like Fe or Mg or (syntheytically Co) the resultant structure is commonly orthorhombic, giving us the orthopyroxene group.
