nephelite
Noun: * A white, gray, or colorless mineral that is a silicate of sodium, potassium, and aluminum. It is a feldspathoid mineral, meaning it is similar to feldspar but contains less silica. Nephelite is found in igneous rocks that are low in silica, such as nepheline syenite.
Nephelite is a technical term used primarily in geology, mineralogy, and industrial contexts. It refers specifically to the mineral itself, its properties, or its occurrence in rock formations. * The geologist identified the pale crystals in the sample as nephelite. * This igneous rock is rich in nephelite and feldspar. * Nephelite is sometimes used as a source of alumina in glass and ceramic production.
