    www.mindat.org/min-6910.html An unusual sulphide mineral that appears to have formed at a very late, or final, stage of metamorphism, after the main event of fenitization, from a highly reduced, subalkaline S-C-H-rich fluid, which may have remobilized Nb as a result of destabilization of oxide minerals (Barkov et al. 2000).

    www.mindat.org/gm/6910 The silvery 1 mm wide crystal belongs to edgarite (analyzed), which grows in a fenitic matrix. The discovery of edgarite has changed our understanding of niobium's geochemistry; it was though to be mostly lithophile, occurring in oxides and silicates; edgarite is a proof for rarely observed chalcophile behaviour of Nb.

    link.springer.com/article/10.1007/s004100050559 Abstract. The new mineral species edgarite, FeNb 3 S 6, was discovered in a feldspar-rich fenite, in a fenitized xenolith enclosed by nepheline syenite of the Khibina alkaline complex, Kola Peninsula, northwestern Russia.It occurs as platy inclusions (up to 0.15 mm) in Ti-(V)-rich pyrrhotite and ferroan alabandite, and as dark gray aggregates of platy grains located on the surface of the ...
