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 (born 1963) 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.https://www.mindat.org/min-29261.html Minerals associated with abramovite at its type locality are wurtzite, sylvite, halite, galena, and anhydrite. https://www.mindat.org/min-29261.html
