About SchwertmanniteHide

Udo Schwertmann
Fe3+16(OH,SO4)12-13O16 · 10-12H2O
brownish yellow
1 - 2
Crystal System:
Originally named glockerite in 1855 by Karl Friedrich Naumann in honour of Ernst Friedrich Glocker (1 May 1783 Stuttgart, Germany - 18 July 1858), professor of mineralogy at University of Breslau (University of Vratislav; Wroclaw, Poland) and author of numerous systematic mineralogical works. Renamed by J.M. Bigham, L. Carlson, E. Murad, in 1994 in honour of Udo Schwertmann (25 November 1927,Stade/Elbe, Germany - 20 January 2016), soil scientist at the University of München (Munich), Germany. He made "numerous contributions to the crystal chemistry of iron oxides and oxyhydroxides and has greatly advanced our knowledge of poorly crystalline phases that are common to weathering environments."
