UM1999-18-OH:Pd

Valid as an unnamed mineral
This page is currently not sponsored. Click here to sponsor this page.
Formula:
Pd(OH)2 or Pd(OH)2 · nH2O
Probably formed by replacement of a Pd-bearing precursor mineral rather than a precipitation from a fluid.

One of many Pd-O compounds, most of which are however unnamed. Compare palladinite.

Co-described with UM1999-14-O:HPd. Also associates with sperrylite, isomertieite, and michenerite.

Possibly the first PGE purely hydroxide mineral. Compare UM2005-19-O:IrOs, UM2005-20-OH:CuIrOsRh, UM2005-21-OH:FeIrPtRh, and UM2005-22-OH:IrPtRh.

Electron microprobe data, wt.% (for the two unnamed species):

Pd 67.85, 50.42
Pt 0.78, 0.00
Fe 1.36, 2.23
Ni 1.60, 1.51
Cu 4.84, 2.83
Bi 1.41, 0.89
S 0.13, 0.06
O 23.29, 40.02
