inosilicate (chain silicate, band silicate). ... Two important groups of rock-forming minerals are included: pyroxenes, where two of the four oxygens are shared to give a 'single chain' structure with the ratio Si : O = 1 : 3; and amphiboles, where half the SiO4 tetrahedra share two oxygens and the other half share three oxygens, to give a 'double chain' or 'band' structure and a ratio Si : O = 4 : 11. 1, record 1, English, - band%20silicate

inosilicate: A class or structural type of silicate characterized by the linkage of the SiO4 tetrahedra into linear chains by the sharing of oxygens. In a simple chain, e.g. pyroxenes, two oxygens are shared; in a double chain or band, e.g. amphiboles, half the SiO4 tetrahedra share three oxygens and the other half share two. The Si:O ratio of the former type is 1:3 and for the latter it is 4:11. 2, record 1, English, - band%20silicate
