Abstract Iron minerals – which behave as indicators in earthly and Martian environments can be identified by UV‐VIS‐NIR reflectance spectroscopy. The aim of this study was to compare the spectra various soils sediments all contain iron but developed under different environmental conditions. To identify mineral we used first second derivatives Kubelka‐Munk transformed spectra. According their composition, analysed samples divided into three distinct groups. Goethite refers hydromorphic conditions, hematite suffers from long intense weathering leaching environment. In case steppe climatic conditions is so weak that appearance pedogenic improbable these soils. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
