Holocene paleodust deposition in south-central Sweden using rain-fed peat bogs as archive
The data is provided in one xlsx file having four tabs: LOI and C, Chemical oxidation, Fig2, Fig3. The same data is also available in four separate csv files. All data files are included in one zip file.
"LOI and C" contains the weights of the samples prior and after combustion at different temperatures and, where measured, also the carbon content of the ash residues.
"Chemical oxidation" contains information about sample weight prior to wet oxidation, weight of Na₂S₂O₈ added, amount of water (ml) and weight of added clay standards and lastly, where measured, residual elemental carbon values after oxidation.
"Fig2" contains the XRD data from the first exploratory part of the study, ie the data from the XRD analysis of one sample subjected to different pre-treatments, as well as XRD data after analysis of different peat samples from Store Mosse oxidised with either H₂O₂ or Na₂S₂O₈. The results from this part of the study where used to design the next, replicate, part of the study where triplicates of a homogenised peat composite where subjected to either combustion at different temperatures or chemical oxidation by Na₂S₂O₈.
"Fig3" contains the data from XRD analysis of the replicates. For each treatment, three samples where used and analysed (in the figure only one representative sample is displayed). The sheet contains the XRD data of the analysed ash residues (combusted at either 300, 350, 400, 450, 500 or 550°C) as well as the XRD data of the chemically oxidised samples. In order to evaluate the effect on more sensitive clay minerals, clay standards where also added to some samples. These samples where also analysed by XRD and are also included in the sheet.
