About Flurlite
Mathias von Flurl
Formula:
Zn3Mn2+Fe3+(PO4)3(OH)2 · 9H2O
Colour:
Bright orange red to dark maroon red
Specific Gravity:
2.89
Crystal System:
Monoclinic
Name:
Named by I.E. Grey, E. Keck, W.G. Mumme, A. Pring and C.M. MacRae in 2014 in honor of Mathias von Flurl (5 February 1756, Straubing, Bavaria - 27 July 1823, Kissingen, Bavaria), the founder of mineralogical and geological studies in Bavaria. He created the first geological map of Bavaria.
Related to schoonerite.
A re-evaluation of the site occupancies in flurlite, using BVS calculations, resulted in a change in the dominant cation in the M1 site from Mn2+ to Zn. Consequently, the end-member formula for flurlite becomes [5]Zn[6]Zn3[6]Fe3+(PO4)3(OH)2(H2O)7·2H2O (CNMNC Newsletter No. 42).
