Baratovite
Radioactive

Baratovite is a very rare cyclosilicate mineral named after Rauf Baratovich Baratov from Tajikistan. It was discovered in 1974 at Dara-Pioz glacier, Tajikistan,[2] and was approved by the International Mineralogical Association only a year later in 1975.[3] The glacier gives home to 133 valid species, and is the type locality of 33 minerals, one of which is baratovite.[2]

Properties

It's a titanium rich variant of

ultraviolet light, it has a blueish white fluorescence.[5] The mineral is similar to muscovite, but can be distinguished by its fluorescence. Baratovite can either be colorless, white, or have pinkish tints. It forms platy deposits up to 5 cms that are nacre-white, and it grows in patchy granular aggregates.[2] The mineral is monoclinic, probably pseudo-hexagonal, which is shown by the single crystal X-ray study. When inspected under a microscope, it can be clearly seen that the mineral is perfectly homogeneous. The mineral has an extremely low anisotropy
.

Occurrences

It's a type locality of Dara-Pioz glacier, Tajikistan, but it also occurs at the Iwagi islet, Japan. It occurs as an accessory mineral. It occurs in the form of veinlets in quartzes, albites and aegirines, and in albitites in syenites. Minerals associated with baratovite vary between localities.

The associated minerals of baratovite specimens found in Dara-i-Pioz massif, Tajikistan are: quartz, albite, ekanite, titanite, aegirine and miserite.

Associated minerals of biotite from Iwagi islet, Japan are: apatite, zircon, pectolite, sugilite, allanite, titanite, aegirine and albite.[2]
