About Bořickýite
Formula:
(Ca,Mg)(Fe3+,Al)4(PO4,SO4,CO3)2(OH)8 · 3-7.5H2O
Colour:
Reddish brown
Lustre:
Waxy
Crystal System:
Amorphous
Name:
Re-named borickite by James Dwight Dana in 1868 in honor of Emanuel Bořický [December 12, 1840 Millin, Bohemia, (Czech Republic) - January 26, 1881 Příbram, Bohemia, (Czech Republic)], systematic mineralogist and petrographer, professor of mineralogy at the University of Prague, who described a similar compound in 1867. Orthography corrected by Rudolf Ignatz Koechlin in 1928. Apparently originally named delvauxene in 1854 by the chemist Karl von Hauer (son of Joseph Ritter von Hauer), but the congruence of the two minerals is unknown.
A questionable mineral, probably identical with Delvauxite, equally doubtful.
Originally reported from Brandberg Mt., Leoben, Styria, Austria.
