Silicate Mineral Structural Styles

This is the basic structure of micas (biotite, muscovite), and also of clay minerals. Finally, when all four oxygens are linked to other tetrahedra, either by oxygen sharing or via an inserted metal ion, we get three-dimensional framework structures. This is the structural style of the mineral quartz, and of the feldspar family of minerals.
