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 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.
