PERISTERITE Meaning and
Definition
-
Peristerite is a term used in mineralogy to describe a specific type of feldspar mineral belonging to the plagioclase series. It is a relatively rare variety of albite feldspar that typically exhibits a distinctive grayish-white or pinkish-white coloration, often with a pearly or iridescent sheen.
The name "peristerite" is derived from the Greek word "peristera," meaning dove, as the color of the mineral is reminiscent of the feathers found on these birds. It is primarily composed of sodium and aluminum silicate, with small amounts of other elements such as calcium and potassium.
In terms of its crystal structure, peristerite belongs to the triclinic system and typically forms in tabular or prismatic crystal habits. It commonly occurs as an accessory mineral in various igneous rocks, particularly in those of granitic or syenitic composition. Peristerite can also be found in association with other minerals such as quartz, biotite, and hornblende.
One of the notable features of peristerite is its ability to exhibit a phenomenon known as labradorescence or schiller effect. This optical effect causes the mineral to display a play of colors, often in blue or green hues, when rotated or viewed from different angles. This unique property makes peristerite a sought-after gemstone for use in jewelry, where it is often cut and polished as a cabochon.
In summary, peristerite is a rare type of albite feldspar that boasts a characteristic grayish-white or pinkish-white coloration with a pearly sheen. It belongs to the triclinic crystal system and is associated with various igneous rocks. Additionally, peristerite can display a labradorescent
