About SimferiteHide

08361930015904439825145.jpg
Simferopol, Ukraine
Formula:
Li(Mg,Fe3+,Mn3+)2(PO4)2
Colour:
Dark red to nearly black
Lustre:
Vitreous, Greasy
Specific Gravity:
3.22 - 3.27
Crystal System:
Orthorhombic
Name:
Found by V.V. Bairakov in the core of a borehole (depth 15 m) in the contact zone of a granite pegmatite body in the Rodionovskoe (Radionovskoye) pegmatite field, Zaporozh'e district Azoz Sea Region, Ukraine. Named after Simferopol City, in Crimea, Ukraine, where the mineral was studied [Pekov 1997].

Both the name simferopolite and simferite was used in the first papers. The name of the city and the mineral is derived from greek, συμφέρω, sympherō, which means to bring together; to be helpful, a common good, as four cations (Li,Mg,Fe,Mn) enter into its structure [Simonov et al 2005].
Related to the Triphylite Group.
