Kudrutite

Kudrutite is a rare mineral belonging to the sulfide class. It is composed of a barium copper sulfide compound, specifically barium dicopper tetrathiocyanate. This mineral was discovered in 1948 in the Ural Mountains of Russia. It is notable for its distinctive blue-black colored flecks within a matrix of lighter color.

In terms of crystal structure, kudrutite forms crystals often in tabular or platy morphology. The composition of the mineral can vary, with coppers and bariums in a mix of squares of hydration and sulfidak crystals. Kudrutite is a soft mineral, which is prone to scratching and damage. It also has a relatively high density of 4.34 to 4.53 g/cm3.

Its crystal structure was first identified and analyzed by researchers in the Soviet Union, culminating in the official classification of the mineral. The mineral is found in hydrothermally altered rocks and occurrences, associated with large geothermal systems at hydrated sulfide deposits. This does not specify any deposits of kudrutite outside its most famous occurrence, but does suggest kudrutite minerals as a trait in related environments.

Kudrutite was recognized and classified by the International Mineralogical Association. This means its distinction amongst other minerals in chemistry, crystal habits, and harder silicates creates its mineral corner within educational materials for geology. The rights of kudrutite were heard in 1948 and it has no confirmable commerce place markets, if any.
