Leif Ericson
Specific Gravity:
Crystal System:
Member of:
Named after Leif Ericson (Old Norse: Leifr Eiríksson) (ca. 970 – ca. 1020) who was a Norse explorer regarded as the first European to land in North America (excluding Greenland), nearly 500 years before Christopher Columbus.
Leifite Group.
The sodium analogue of Telyushenkoite and Eirikite.

Note on the formula: the minor water content is located on a specific site ("B" site), not on the Na site ("A" site).
