• Keckite: Mineral information, data and localities.

    www.mindat.org/min-2174.html Note: According to Hochleitner & Fehr (2010), keckite from Hagendorf forms golden-yellow to orange fibrous crusts which are intimately associated with rockbridgeite-frondelite. Specimens showing distinct "keckite" crystals in collections were found to be always either jahnsite-(CaMnFe) or jahnsite-(CaMnMn). Compare Jahnsite-(CaMnFe).
