Lituolite is a rare mineral discovered in the 1960s, with a complex chemical composition—(Fe,Mn,Mg)2(SO4)3—and a unique spelling. It is pronounced /lɪtjuːəlaɪt/ using the International Phonetic Alphabet (IPA), with stress on the second syllable. The spelling of lituolite follows the tradition of mineralogy nomenclature, which often uses both Greek and Latin roots. The word derives from Greek "λίθος" (lithos), meaning stone, and Latin "lithos" and "liutum" (clay), referring to the mineral's color and composition.
Lituolite is a rare and unique mineral that falls under the category of rock forming minerals. It is generally classified as an alteration mineral, formed through the metamorphic process. The term 'lituolite' is derived from the Latin word 'litulus,' which translates to 'little vessel' or 'small tube.' This name refers to the distinct tubular or cylindrical shape that the mineral commonly displays.
The mineral composition of lituolite primarily consists of various silicate compounds, notably including aluminum, sodium, and potassium. Its characteristic appearance features a dense, fibrous structure, usually with a smooth and glassy surface. Lituolite is aesthetically appealing due to its inherent color range, which can span from white and light gray to pale green, pink, or even deep blue.
Lituolite is primarily found in regions of high metamorphic activity, typically associated with regional metamorphism or contact metamorphism. It is formed under intense heat and pressure conditions, often in the presence of hydrothermal fluids. Lituolite is commonly found in association with other metamorphic minerals such as garnets, staurolite, and kyanite.
Due to its scarcity and unique appearance, lituolite holds some value as a decorative or collector's mineral. However, its applications in industrial or technological fields are limited. Lituolite does not possess any significant industrial uses or commercial importance. It is mostly treasured for its aesthetic qualities and rarity, making it a sought-after addition to mineral collections and lapidary creations.
A genus of minute foraminifera having a spiral form, and straight prolonged outer whorl.
