yes all triangular pyramids are tetrahedra!!!!!!!!!!!!!
It is a type of silicates in which all four oxygen atoms of the silicate tetrahedra are shared with neighboring tetrahedra.
Silicon-oxygen tetrahedra with each tetrahedra sharing the oxygen atoms to give it the structure of SiO2 overall.

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.
Another name is tetrahedra
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.
tetrahedra (a pyramid with a triangular base)
Not exactly. A tetrahedron is a polyhedron. Many tetrahedra are polyhedra.
for what number of tereahedra exist kaleidocycle
The simple answer is... Feldspar has a much higher complex and stable tetrahedral orientation in comparison to that of any other Silicate variation higher up on the reation series latter. Feldspar is one of the most stable variations in orientation of, what boils down to, silicate tetrahedra. Because Feldspar is technically a form of silicate tetrahedra orientation, I am assuming you are asking how the silicate tetrahedra orientations vary from its most simple (i.e. Olivine) to its mosts complex (i.e. quartz/FELDSPAR) forms. Esentially a Silicate Ion SiO4^-4 is the most basic building block of FELDSPAR. Knowing this, as you move from the top of Bowen's reaction series, we see a gradual stabilization of the various Silicate tetrahedral orientations. These orientations include (in order of stability/complexity): [TOP OF REACTION SERIES] Individual (Singular form) Silicate Tetrahedra (i.e. Olivine) Chain (Linear form) Silicate Tetrahedra (i.e. Pyroxine) Double Chain (Bilinear form) Silicate Tetrahedra (i.e. amphibole) Sheet Silicate Tetrahedra ('2-D' form) (i.e. Mica: Biotite or Muscovite) Framework Silicate Tetrahedra ('3-D' form) (i.e. FELDSPAR) [BOTTOM OF REACTION SERIES]
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.
