Neptunite - Wikipedia
Neptunite is a silicate mineral with the formula K Na 2 Li (Fe 2+, Mn 2+) 2 Ti 2 Si 8 O 24. With increasing manganese it forms a series with mangan-neptunite. Watatsumiite is the variety with vanadium replacing the titanium in the formula. It was first described in 1893 for an occurrence in the Narssârssuk pegmatite of West Greenland. [3] .
