Formula:

Fe3+6O4(OH)8[CO3] · 3H2O

Specific Gravity:

2.950 (Calculated)

Name:

Named after Professor Rudolf Ludwig Mössbauer (31 January 1929 Munich – 14 September 2011 Grünwald, Germany) who discovered the resonance of γ rays that bears his name, for which he was awarded the 1961 Nobel Prize in physics. Without this technique, the very existence of this mineral in gleysols and the true nature of the ‘green rust’ compounds could not be understood

Hydrotalcite supergroup. It has a layered double hydroxide-type structure, in which brucite-like layers [Fe3+6O4(OH)8]2+ are intercalated with CO32- anions and water molecules.

The fully oxidized analogue of fougèrite and trébeurdenite, related to them chemically by the exchange of (Fe3+O2−) with (Fe2+OH−).

Synchrotron X-ray data indicate that the natural material is a nanoscale intergrowth of 2T and 3T polytypes; the latter probably has the 3T7 stacking sequence.
