Abramovite


Abramovite is a very rare mineral from the sulfides and sulfosalt categories. It has the chemical formula Pb2SnInBiS7. It occurs as tiny elongated lamellar-shaped crystals, up 1 mm × 0.2 mm in size, and is characterized by its non-commensurate structure.

Etymology and history

Abramovite is named after the mineralogist Dmitry Vadimovich Abramov of the Fersman [Mineralogical Museum|A.E. Fersman Museum], Russia.
It was discovered as fumarole crust on the Kudriavy volcano, Iturup Island, Kuril Islands, Russia.

Formation

Abramovite is a product of precipitation from fumarolic gases in an active stratovolcano.

Type occurrence

Abramovite comes in small metallic aggregates less than 1 mm across. Abramovite is conserved at A.E. Fersman Mineralogical Museum, Russian [Academy of Sciences], Moscow.
The type locality for abramovite is Kudriavy volcano.
Minerals associated with abramovite at its type locality are wurtzite, sylvite, halite, galena, and anhydrite.
