tasoneule

Tasoneule is a rare and complex mineral that was first discovered in the late 19th century. It is named after its discoverer, the French mineralogist, Pierre Tasoneule. The mineral is characterized by its unique crystal structure and distinctive coloration, which ranges from pale yellow to deep orange. Tasoneule is typically found in low-temperature hydrothermal veins, often in association with other minerals such as quartz and calcite.

The chemical composition of tasoneule is (Fe,Mg)2(SiO4)(OH)2, which indicates that it is a member of the silicate mineral group. Its structure consists of layers of iron and magnesium ions sandwiched between layers of silicate tetrahedra, with hydroxide ions occupying the interlayer spaces. This structure gives tasoneule its characteristic layered appearance under the microscope.

Tasoneule is of limited economic importance due to its rarity and the small size of its crystals. However, it is valued by collectors and mineral enthusiasts for its aesthetic appeal and the challenge of finding and identifying it in the field. The mineral's rarity and the specific conditions under which it forms make it a subject of interest for geologists and mineralogists studying the processes of mineral crystallization and the geochemistry of hydrothermal systems.
