ø Feldspar | The Gemstone List ø

Feldspars are the most common mineral on earth, forming around 60% of the earth's crust. Feldspar has the chemical formula xAl(Al,Si) 3 O 8 - or "x aluminium silicate" in which x can be sodium, calcium, potassium, or a combination of these in varying quantities, forming a series known as a "solid solution". Feldspars are usually light colored and cleave well along structural planes.

Feldspar - Identification of specific feldspars: Alkali feldspars can often be distinguished from plagioclase feldspars because most grains of the latter exhibit albite twinning (see above Crystal structure), which is manifested by parallel lines on certain cleavage surfaces, whereas grains of alkali feldspars do not. This criterion is not, however, absolute; some plagioclase feldspars are not ...

Feldspar | Encyclopedia.com

Feldspar is less chemically stable when exposed to water than quartz, the other major ingredient of granite. Granite exposed to weather therefore becomes crumbly as its feldspar decays, and mechanical forces (e.g., wind, running water) break the granite up into sand. Rough, rapid fragmentation liberates some feldspar before it has had time to ...

Plagioclase - Wikipedia

Plagioclase is a series of tectosilicate (framework silicate) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series (from the Ancient Greek for "oblique fracture", in reference to its two cleavage angles).
