The mineral anorthoclase ((NaK)AlSi3O8) is a crystalline solid solution in the alkali feldspar series in which the sodium-aluminium silicate member exists in larger proportion. It typically consists of between 10 […]

Plagioclase is an important series of tectosilicate minerals within the feldspar family. Rather than referring to a particular mineral with a specific chemical composition plagioclase is a solid solution series […]

Orthoclase (endmember formula KAlSi3O8) is an important tectosilicate mineral which forms igneous rock. The name is from the Greek for straight fracture because its two cleavage planes are at right […]

Peridot (/ˈpɛrɨdoʊ/ or /ˈpɛrɨdɒt/) is gem-quality olivine. Olivine is a silicate mineral with formula of (Mg Fe)2SiO4. As peridot is the magnesium-rich variety (forsterite) the formula approaches Mg2SiO4.

The mineral olivine (when of gem quality it is also called peridot and chrysolite) is a magnesium iron silicate with the formula (Mg+2 Fe+2)2SiO4. It is a common mineral in […]
