Raw XRD data from: Fe-nodules from the southern Baltic Sea. Morphology, mineralogy and geochemistry

Raw XRD data from research paper "Fe-nodules from the southern Baltic Sea: morphology, mineralogy and geochemistry". These are raw *.xrdml files which may be opened by notepad (in Windows OS) or Profex software (open-source).For the analysis of the samples, X-ray diffraction in the Bragg-Brentano configuration was employed using an X'Pert PRO MPD diffractometer (PANalytical B.V., Netherlands) equipped with a cobalt anode tube and an iron filter. The samples were dried, crushed, and ground into powder (90% of particles ≤ 80 μm) using an agate mortar and pestle. The powdered samples were pressed into thin pellets using a back-loading method. Diffractograms were recorded over the angular range of 4° to 78° (2θ) using Co Kα radiation, with a voltage of 40 kV and a current of 30 mA, at a measurement step size of 0.026°/min and a step time of 2 seconds. The total analysis duration was 4 hours.
