Covering 76005. Burial mound 76. Iberian cemetery of Tutugi

Red and white covering 76005 located in the corridor of the burial mound 76 of the cemetery of Tútugi (Galera, Granada, Spain). The identification of hematite (Fe2O3) by MRS and the high concentration of Fe (7.05% wt according to EDXRF analysis) explain the origin of the red color. The white layer of the covering is manufactured with gypsum (CaSO4·2H2O).

Non destructive. Surface cleaning. Sample pretreatment is not required. Direct measurement.

Energy dispersive X- ray fluorescence (EDXRF)

EDAX (model Eagle III) fluorescence spectrometer (CITI, University of Seville). This spectrometer is equipped with a microfocus X-ray tube with an Rh anode, a polycapillary lens for X-ray focussing, and an 80 mm2 energy dispersive Si-(Li) detector. The sample chamber incorporates an XYZ motorized stage for sample positioning. A high resolution microscope is used to position the sample on the desired distance from the polycapillary. To increase the sensitivity of the low Z elements, the sample chamber can be brought under vacuum. For the analysis of the samples, a spot size of 300 µm was chosen at an operating X-ray tube voltage of 40 kV. The tube current was adapted for each sample in order to optimise the detection of X-rays.
