Abstract:
The XRD data has been gained from pulverized and homogenized samples each centimeter of core PS72/413-3 GKG by AWI personal at AWI core labs supervised by Drs. Jutta Wollenburg and Jens Matthiessen. XRD raw measurements were run at Crystallography, Geosciences, University of Bremen in 2016-2017. Measurement conditions: Philips X'Pert Diffractometer, Cu radiation, fixed divergence, secoundary Ni filter, 3-85 ° 2theta, 0.0016° step size, 100 sec calculated step time. XRD mineral assemblage determination were subsequently gained through the QUAX full pattern quantitative determination software (see Vogt et al. 2002 at Pangaea methods wiki). The software allows for differentiation of all carbonate minerals incl. Mg-rich calcite. For comparison reasons the d-value for Mg-rich calcite is also given. A QXRD investigation allows for not only identification of mineral content but also for detailing authigenic vs. allochthonous minerals, transport of detrital input to the sediment core and the interpretation of the transport processes and the local environment as well as the paleoceanographic reconstruction of the region. Sediment ages are given through the below mentioned data sets.
