Abstract

This article is devoted exclusively to three iron minerals that have a decisive influence on the colour of the ‘Poznań Clays’. These are hematite, goethite, and jarosite. Their presence gives the ‘Poznań Clays’, which are the most common and best known Neogene lithostratigraphic unit in the Polish Lowlands, characteristic ‘warm’ colours ranging from yellow through orange to dark red. The presented results were mainly obtained using powder X-ray diffraction and 57Fe Mössbauer spectroscopy.
