A silicate mineral that shares it's oxygen atom with another silica tetrahedron, forming a chain of tetrahedra. Single chain silicates include a group called the pyroxenes.
Platinum is a non-silicate mineral. It is classified as a native element, meaning it is composed of only one type of atom and does not contain silicate structures. Unlike silicate minerals, which are based on silicon-oxygen tetrahedra, platinum occurs in its pure metallic form and does not form silicate compounds.
Dolomite is not a silicate; it is classified as a carbonate mineral. Silicates are minerals that contain silicon and oxygen, typically forming structures like silicate tetrahedra. In contrast, dolomite is composed primarily of calcium magnesium carbonate (CaMg(CO₃)₂), which does not include silicon in its structure. Thus, while it contains oxygen and carbon, its lack of silicon disqualifies it from being a silicate.
The five types of silicate structures are: Nesosilicates: Isolated tetrahedra, such as olivine. Sorosilicates: Pair of tetrahedra sharing one oxygen atom, like epidote. Cyclosilicates: Tetrahedra arranged in rings, exemplified by beryl. Inosilicates: Tetrahedra linked in single or double chains, as seen in pyroxenes and amphiboles. Phyllosilicates: Tetrahedra forming sheets, with examples including mica and talc.
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.
Silica tetrahedra in silicate minerals are linked together by sharing oxygen ions at the corners of the tetrahedra. This creates a strong network structure known as a silicate framework that gives the mineral its physical and chemical properties. The arrangement and bonding of these tetrahedra determine the crystal structure and properties of the silicate mineral.
The specific molecule that makes up the silicate mineral family is the silicate anion, which consists of silicon and oxygen atoms bonded together. Silicon-oxygen tetrahedra are the building blocks of all silicate minerals.

The elements are Silicon (Si) and Oxygen (O).
Silicate tetrahedra. The tetrahedra are spanned by oxigen atoms, and right in the middle, there is a silicon atom. The chemical formula for one silicate tetrahedron is SiO4 The actual rate between silicon and oxigen can change as the tetrahedra are linked together, as different tetrahedra can share an oxigen atom with eachother.
It is a type of silicates in which all four oxygen atoms of the silicate tetrahedra are shared with neighboring tetrahedra.
A silicate mineral must contain silicon and oxygen as its primary components. These elements form the building blocks of silicate minerals, with other elements such as aluminum, iron, magnesium, and calcium often present in smaller quantities. Silicate minerals are the most abundant mineral group on Earth and have a structure based on silicon-oxygen tetrahedra.

Thus, while it contains oxygen and carbon, its lack of silicon disqualifies it from being a silicate.
Non-silicate minerals don't contain silicon and oxygen in tandem; silicate minerals do.
A structural type of silicate mineral in which flat sheets are formed by the sharing of three of the four oxygen atoms in each tetrahedron with neighboring tetrahedrons. Also known as layer silicate; sheet mineral; sheet silicate.
Pyrite is a non-silicate mineral. It is a sulfide mineral composed of iron and sulfur, not containing silicon and oxygen as found in silicate minerals.
