Petalite and Analcime
Analcime and Feldspar
Petalite and Quartz
feldspar and quartz
Feldspar and quartz are the two most common silicates. In beryl, the silicate pyramids join together as rings. Biotite is mica. The silicate pyramids come together to create thin, flexible sheets. Compare the beryl and the biotite pictured below ( Figure below ).
