Pautovite is a rare mineral that belongs to the family of phosphate minerals. It was first discovered in 2004 in the Sakha Republic, Russia, and is named after its discoverer, Sergey V. Pautov. Pautovite is typically found in hydrothermal assemblages within alkaline pegmatites, which are coarse-grained igneous rocks.
In terms of its physical properties, pautovite is usually found in the form of well-developed prismatic crystals. These crystals can range in color from light brown to pale yellow. Pautovite has a Mohs hardness of 4.5-5, making it relatively soft on the mineral hardness scale. It is also characterized by its vitreous luster and transparent to translucent appearance.
Chemically, pautovite is composed primarily of calcium, titanium, phosphorus, and oxygen, with the chemical formula CaCu(Pb,AsO4)(OH,Cl). This composition places it within the apatite group of minerals. Pautovite is known for its unique crystal structure, which consists of distorted tetrahedral phosphate groups bonded together.
Due to its rare occurrence and limited availability, pautovite has little economic significance. However, it is highly valued by mineral collectors for its aesthetic beauty and the challenge it poses in obtaining specimens. Its distinctive crystal habit and attractive coloration make it a sought-after addition to mineral collections worldwide.
In conclusion, pautovite is a rare calcium titanium phosphate mineral that forms in hydrothermal environments. It is prized for its unique crystal structure, beautiful coloration, and collectability within the mineral enthusiast community.
