Specific Gravity:
3.943 (Calculated)
Crystal System:
Orthorhombic
Name:
Named in honour of Victor Victorovich Sharygin (b.1964) from the Sobolev Institute of Geology and Mineralogy, Novosibirsk, Russia. He is a mineralogist, and expert on alkaline and pyrometamorphic rocks. He worked on xenolith specimens with sharyginite from Eifel and published some preliminary data on the mineral.
