WebSep 11, 2024 · These silicates are divided into several groups based on how the silicate anion present is structured. While we have several groups as stated, the largest groups of silicates are known as the framework silicates. These particular silicates type make up the bulk of the earth crust. Example of these kinds of silicates are quartz and feldspar WebA subclass of the Silicates. The Tectosilicate Subclass is often called the "Framework Silicates" because its structure is composed of interconnected tetrahedrons going outward in all directions, forming an intricate framework analogous to the framework of large building. In this subclass all of the oxygens are shared with other tetrahedrons ...
