Formula:

Fe2+2Fe3+4O2(OH)10CO3 · 3H2O

Name:

Named for the township of Trebeurden, near the maritime marsh where the mineral was first found.

The mineral formerly described as fougèrite has been found to be an intimate intergrowth of two phases with distinct Fe2+:Fe3+ ratios. The phase with Fe2+:Fe3+ = 2:1 retains the name fougèrite; that with Fe2+:Fe3+ = 1:2 is defined as the new species trébeurdenite. Both belong to the Fougèrite Group (Mills et al., 2012).
