N2 - Hydrothermal iron ores from the Fen central complex may be classified according to their mineral assemblages as primary (magnetite + or - pyrite + or - anatase + calcite) or secondary (hematite + or - goethite + calcite + or - dolomite). Primary ores equilibrated between hematite-magnetite and magnetite-pyrite-pyrrhotite buffers at T < 600oC. Alteration to form the secondary parageneses took place above the hematite-magnetite buffer, probably at lower T.
