BIDEAUXITE Meaning and
Definition
-
Bideauxite is a rare mineral that belongs to the family of silicates. It is named after Dr. Blaise E. Bideaux, an American mineralogist, in recognition of his contributions to the field of mineralogy. Bideauxite is typically found as a secondary mineral in phosphate-rich granite pegmatites or in hydrothermal vein deposits formed by the alteration of primary phosphate minerals.
The mineral is characterized by its distinctive crystal structure and physical properties. Bideauxite commonly occurs as small, prismatic crystals or as powdery aggregates. It exhibits a translucent to opaque appearance with a color ranging from white to pale yellow. The crystal system of bideauxite is orthorhombic, and it usually crystallizes in tabular or acicular forms.
Chemically, bideauxite is composed mainly of calcium, aluminum, phosphate, and hydroxide ions. Its chemical formula is usually represented as Ca2Al3(PO4)2(OH)10·6H2O. The presence of water molecules in the mineral structure contributes to its characteristic luster and forms part of its hydration chemistry.
Bideauxite is a relatively uncommon mineral and is not of significant economic value. However, it is highly valued by mineral collectors and researchers due to its rarity and unique crystal habit. Its identification often requires specialized analytical techniques like X-ray diffraction or electron microscopy.
In summary, bideauxite is a rare mineral that occurs in certain geological environments, exhibiting distinctive crystal forms and chemical composition.
