framework silicate

This term is a technical classification used in mineralogy and geochemistry to describe tectosilicates. It refers to a specific structural arrangement where the three-dimensional network of tetrahedra provides high stability and resistance to weathering, which is why minerals like quartz are so prevalent in the Earth's crust.

In a professional geological context, the term is used to distinguish these minerals from other silicate structures such as chain, sheet, or single-tetrahedra silicates. It is a precise scientific descriptor rather than a general term, and it is almost exclusively found in academic or technical literature.
