SPIROLINITE Meaning and
Definition
-
Spirolinite is a mineral that belongs to the silicate family, specifically the phyllosilicates group. It is classified as a rare and unusual mineral with a unique crystal structure. The term "spirolinite" is derived from the Latin word "spira," meaning coil or spiral, and refers to the peculiar twisted and helical formation of its crystal structure.
The mineral typically occurs in thin, twisted fibers or ribbons, which give it a distinct appearance under the microscope. It is often found as aggregates within fractured rocks or filling voids in hydrothermal veins. Spirolinite commonly exhibits a pale yellow to orange-brown color, although variations in hue may occur depending on impurities present.
Chemically, spirolinite consists of hydrated calcium and aluminum silicate with the chemical formula CaAl2Si3O10(OH)2·(H2O). Its crystal structure is formed by interconnected tetrahedra and octahedra units, creating a three-dimensional framework. These units are arranged in such a way that they twist around a central axis, producing the spiral morphology for which the mineral is named.
Due to its limited occurrence and unique crystal structure, spirolinite is highly sought after by researchers and collectors alike. Its twisted fibers and helical formations make it a fascinating mineral to study under both optical and electron microscopes. Its intricate structure and attractive appearance contribute to its value as a collector's mineral, further enhancing its appeal within the mineralogical community.
