Abstract

Single crystal elastic moduli have been measured for several silicates by using Brillouin scattering techniques. These data have been examined to distinguish the roles of composition and crystal structure in defining these moduli. Specific conclusions include the following: 1) the variations in elastic character of two aluminosilicates are related to variations in the crystal structure; 2) elastic properties of pyroxenes are more sensitive to structural characteristic than to substitution of calcium or iron for magnesium; and 3) the elastic character of oxides and silicates are sensitive to the replacement of alkaline earth cations by transition metal cations, yielding a different behavior of bulk modulus and shear modulus on molar volume.-Author
