Rock-forming minerals of the amphibole group resemble the pyroxenes in chemical composition and in the general properties. They are inosilicates because Amphiboles are chain silicates with tetrahedral organization.They are composed of double-chains of SiO4 tetrahedra (hence the name "double-chain silicate"). The standard amphibole formula A 0.1 B 2 C 5 T 8 O 22 (OH) 2 remains unchanged, but the order of allocation of the cations has become even more critical than previously. F. R. Boyd's attempts to synthesize minerals of the general formula (Mg,Fe) 7 Si 8 O 22 (OH) 2 during 1956-1957 showed that the orthorhombic varieties richer in iron than Mg50Fe50 could not be made.
