Tektosilikaatteilla
Tektosilikaatteilla, also known as tectosilicates, are a group of silicate minerals characterized by the presence of isolated SiO4 tetrahedra in their crystal structures. These tetrahedra are not linked to each other, unlike in other silicate groups such as nesosilicates, sorosilicates, and cyclosilicates. The term "tectosilicate" is derived from the Greek words "tectos," meaning "built," and "silikos," meaning "flint," reflecting the isolated nature of the silica tetrahedra.
Tektosilicates are further divided into two main subgroups: framework tectosilicates and sheet tectosilicates. Framework tectosilicates have
These minerals are abundant in the Earth's crust and play significant roles in various geological processes.
The study of tektosilicates is crucial for understanding the Earth's geological history and the formation of
