Granite

Granite is a light-colored plutonic rock found throughout the continental crust, most commonly in mountainous areas It consists of coarse grains of quartz (10-50%), potassium feldspar, and sodium feldspar These minerals make up more than 80% of the rock Other common minerals include mica (muscovite and biotite) and hornblende (see amphibole)...

Momentive

Mechanical properties of fused quartz are much the same as those of other glass The material is extremely strong in compression, with design compressive strength of better than 11 x 10 9 Pa (160,000 psi) Surface flaws can drastically reduce the inherent strength of any glass, so tensile properties are greatly influenced by these defects...

The Quartz Page: Quartz as a Rock

For example, a rock that is entirely made of albite, NaAlSi 3 O 8, a feldspar, has 0% quartz content, but contains 773% silica (weight percent) It was once customary to express the chemical composition of a mineral as an oxide formula (mostly because the structural relationships between the elements involved were not precisely known), and it is still useful if one reflects the silica content...
