Double chain silicate
When two single chains of tetrahedra bond to each other, the resulting structure is called a double chain silicate. These structures typically involve each tetrahedron sharing three oxygen atoms with adjacent tetrahedra, forming a linked double chain. Examples include amphiboles and pyroxenes.
Chain silicates have interlocking chains of silicate tetrahedra. When adjacent tetrahedrons share either two oxygen's to continue the chain, or three oxygen atoms to connect also to a second chain, double chains are formed.
The result is called a diamond structure. Diamond consists of tetrahedrally bonded carbon atoms arranged in a three-dimensional network structure, making it one of the hardest known materials.
When each tetrahedron shares three of its oxygen atoms with other tetrahedra, a framework silicate structure is formed. This structure results in a three-dimensional network of interconnected tetrahedra, giving rise to minerals such as quartz and feldspar.
Yes. Carbon atoms form to create certain types of chains. Straight Carbon Chains, Branched Carbon Chains, and Carbon Rings. Carbon can form single, double or triple bonds. You're welcome

The mineral example you're referring to is olivine. Olivine has a simple structure consisting of single silica tetrahedra linked by atoms of magnesium and iron.
When two single chains bond to each other, the result is typically the formation of a larger, more complex molecule, often referred to as a polymer if the chains are long. This process can involve various types of bonding, such as covalent, ionic, or hydrogen bonding, depending on the nature of the chains involved. The interaction can lead to changes in physical and chemical properties, enhancing the material’s strength, flexibility, or other characteristics.

Isolated tetrahedra silicates do not link with other silicon or oxygen atoms Ring Silicates form by sharing oxygen atoms Single Chain Silicates form a chain when sharing oxygen atoms Double Chain Silicates form when two or more single chains of tetrahedra bond to each other Sheet Silicates form when each tetrahedron shares three of its oxygen atoms with other tetrahedra Framework Silicates form when each tetrahedron is bonded to four other tetrahedras :)
Hornblende and other amphiboles have a double chain silicate structure, where silicon-oxygen tetrahedra are connected in double chains linked by other cations like aluminum, magnesium, and iron ions. This structure gives amphiboles their distinct prismatic shape and cleavage properties.
A single silicon-oxygen tetrahedron is typically not stable on its own and tends to polymerize or form interconnected structures with other tetrahedra. They are the building blocks of various silicate minerals and have a net charge of -4. Silicon-oxygen tetrahedra are not found in isolation but are connected to form complex networks in minerals.
Garnet is an example of a mineral that has a basic structure consisting of isolated tetrahedra linked by atoms of other elements. In garnet, each tetrahedron shares oxygen atoms with neighboring tetrahedra, creating a three-dimensional framework. The cations occupying the spaces in between the tetrahedra give garnet its characteristic structure and properties.
The result is called a diamond structure. Diamond consists of tetrahedrally bonded carbon atoms arranged in a three-dimensional network structure, making it one of the hardest known materials.
Isolated tetrahedra are linked with silicate minerals such as olivine and garnet, where each tetrahedron shares no oxygen atoms with neighboring tetrahedra. This results in these minerals having higher densities and more complex crystal structures compared to other silicate minerals.
