  • Mineral Gallery - The Inosilicate Subclass

    www.galleries.com/minerals/silicate/inosilic.htm The Inosilicates include two distinct groups: the single chain and double chain silicates. In the single chain. group the tetrahedrons share two oxygens with two other tetrahedrons and form a seemingly endless chain.. The ratio of silicon to oxygen is thus 1:3. The tetrahedrons alternate to the left and then to the right along the line formed by the linked oxygens although more complex chains ...
