Just one little specimen with analysed Magnesioferrite in my collection .... and that is necessary .... analysing !! Because you really can't see on sight whether certain crystals are ... Hematite .. Magnetite ... or Magnesioferrite !! Günter Blass (Eschweiler) was so kind to analyse this specimen. The EDX result: 45% Mg - 49% Fe - 5% Al - 1% Mn. Magnesioferrite is the third mineral from the "Spinel group" you cand find at the Wannenköpfe. The other ones are Magnetite and Spinel, both also very rare.
