Study Notes
Silicate Mineral Classification
- Independent Tetrahedra: Tetrahedra that do not share any oxygen atoms; connected through cations.
- Single Chains: Tetrahedra link in a chain formation by sharing two oxygen atoms.
- Double Chains: Tetrahedra form interconnected chains sharing two or three oxygen atoms.
- Sheet Silicates: Tetrahedra share three oxygen atoms, creating layered structures.
- Framework Silicates: Tetrahedra share all four oxygen atoms, resulting in a three-dimensional framework.
Examples of Silicates
- Independent Tetrahedra: Represented by the mineral garnet.
- Single Chains: Characterized by pyroxenes, important rock-forming minerals.
- Double Chains: Found in amphiboles, which are significant in igneous and metamorphic rocks.
- Sheet Silicates: Comprising micas and clays, commonly found in sedimentary environments.
- Framework Silicates: Includes quartz and feldspar, essential minerals in many geological processes.
