XRD analysis of Iberian unfired potsherds from the Late Iron Age (Q9973)

This dataset contains 11 mineralogical analyses of ceramic potsherds by powder X-ray diffraction (XRD). The samples come from the Iberian workshop of the Mas de Moreno (Teruel, Spain). Method The outer surfaces of all the samples were mechanically removed prior to analysis. All samples were manualy powdered in an agate mortar. The data were collected with a D8 Advance (Bruker) diffractometer in Bragg-Brentano configuration working at 1.6 kW (40 kV, 40 mA) and equipped with a copper anode source (k1 = 1.5406 ; the k ray being removed by a Ni-filter in the diffracted beam). An 8 mm anti-scattering slit was mounted in front of the LynxEye CCD detector. The explored area covered the 3-70 (2) range, with an angle step of 0.02 and a time step of 2 seconds. The stability of the instrument was checked between the different series of measurements by analyzing a standard (corundum crystal, NIST 1976). Data description File format: Bruker raw. The "XRD_clay_raw.zip" archive contains the raw diffractograms. All file names start with the sample code (a code starting with "BDX" followed by a 5-digit number), followed by a capital "P" (for powder diffraction). The "XRD_clay_raw.csv" file contains all results expressed in counts, one sample per row. The first column gives the angular position (2 thta).
