dc.description.abstract-en | Hydrothermal experiments aimed at the synthesis of trioctahedral femrginous Cs micas were carried out at 100 MPa and
a constant temperature in the range 500-710°C or in a temperatue gadient. Starting mixes consisted of SiO2, Fe2O3, Al2O3,
Cs2CO3; there was excess water in all runs, and in some runs also an excess of CsOH or Cs2CO3, in solution. Two micas were
grown with good yields, the Cs analog of annite and the Cs analog of tetra-ferri-annite. The former is usually accompanied
by variable quantities of pollucite (t magnetite) or fayalite. An almost Al-free "Cs-tetra-ferri-annite" was synthesized from
an aluminous mix in thermal gradient runs, and a pure "Cs-tetra-ferri-annite" was synthesized from an Al-free oxide mix.
Rieweld refinement of the structure of "Cs-annite" shows it to be similal' to the structures of annite. tetra-ferri-annite, and
"Cs-tetra-ferri-annite", which has the largest unit-cell of any mica synthesized to date. | en |
