About Liversidgeite
Formula:
Zn6(PO4)4 · 7H2O
Colour:
Colourless, white
Lustre:
Vitreous
Hardness:
3 - 3½
Specific Gravity:
3.21
Crystal System:
Triclinic
Name:
Named in 2010 by Peter Elliott, Gerald Giester, Eugen Libowitzky, and Uwe Kolitsch in honor of Archibald Liversidge (November 17, 1847, Chiswick, England – September 26, 1927, London, England), Professor of Geology and Mineralogy, and later Professor of Mineralogy and Chemistry at the University of Sydney. The name is in recognition of his contributions to the study of the mineralogy of New South Wales, in particular that of the Broken Hill deposit, and also recognises his contribution to science education, especially in mineralogy and chemistry.
