Harm Bartholomeus, Gerrit Epema, Michael Schaepman
2007 International Journal of Applied Earth Observation and Geoinformation  
The possibility of quantifying iron content in the topsoil of the slopes of the El Hacho Mountain complex in Southern Spain using imaging spectroscopy is investigated.  ...  The spatial distribution of iron in vegetated areas shows a strong sensitivity of these relations with the presence of vegetation.  ...  We acknowledge the use of the spectrometers from the Meetkundige Dienst Rijkswaterstaat and Radboud University Nijmegen.  ...

The magnetic properties of Quaternary aeolian dusts and sediments, and their palaeoclimatic significance

B.A. Maher
2011 Aeolian Research  
The magnetic record for a sediment sequence may reflect changes in sediment source, and diagenetic (post-depositional) loss and/or transformation and/or gain of magnetic minerals.  ...  Magnetic measurements, sensitive even to trace concentrations of these iron minerals, can readily discriminate between different magnetic mineral assemblages, and are also relatively rapid, non sample-destructive  ...  Simon Chew and Gemma Davies assisted greatly with the diagrams. I also appreciate the patience and helpfulness of the journal editors.  ...
