Allabogdanite is a very rare phosphide mineral with the chemical formula, found in 1994 in a meteorite.[2] [5] It was described for an occurrence in the Onello meteorite in the Onello River basin, Sakha Republic; Yakutia, Russia; associated with taenite, schreibersite, kamacite, graphite and awaruite.[2] It was named for Russian geologist Alla Bogdanova.[3]
In a June 2021 study, scientists reported the discovery of terrestrial allabogdanite in a sedimentary formation. It is located in the Negev desert of Israel, just southwest of the Dead Sea.[4]
