Study Notes
Silicate Minerals: Classification and Examples
- Silica tetrahedron is a four-sided molecule with one silicon atom and four oxygen atoms arranged in a tetrahedral structure
- Silicate minerals are categorized based on the bonding of silica tetrahedra to each other and to other elements
- Nesosilicates, also known as orthosilicates, have isolated silica tetrahedra bonded to cations like forsterite and tephroite
- Sorosilicates are formed when two tetrahedra are linked by one oxygen atom, as seen in hemimorphite
- Cyclosilicates form rings with shared oxygen atoms, leading to high hardness and luster, exemplified by cyclosilicate minerals
- Inosilicates can be single or double chain formations, with two oxygen atoms shared between tetrahedra
- Phyllosilicates have sheet-like structures formed by linked rings of tetrahedra, as seen in minerals like talc
- Tectosilicates, such as feldspar, have a complex three-dimensional structure with interconnected tetrahedra
- Quartz, the second most abundant mineral in Earth's crust, is formed from slowly cooling magma and consists of oxygen and silicon
- Feldspar minerals, comprising more than half of Earth's crust, contain alumina and silica
- Mica minerals have a two-dimensional sheet structure and perfect basal cleavage, exemplified by minerals like galena
- Amphibole minerals, found in metamorphic and igneous rocks, have high silica content and are composed of silicates combined with metals like magnesium and iron
