Rectangular structure MT7-4. Oppidum Puente tablas

Rectangular estructure located in the room 2 of the house 7 of the Iberian oppidum of Puente Tablas (Jaén, Spain). It was made during the final phase of occupation of the house using gypsum (CaSO4·2H2O). The anlaysis by MRS also shows residual calcite (CaCO3).

Micro-Raman Spectroscopy (MRS);

Renishaw ‘in via’ Reflex Spectrometer coupled with a confocal Leica DM LM microscope (CICT, University of Jaén), equipped with a diode laser (785 nm, 300 mW), and a Peltier-cooled CCD detector, calibrated to the 520.5 cm-1 line of silicon.

X-Ray Difraction

Mineral analysis of the container

XRD analysis used the method of crystalline powder. The samples were ground to powder in an Agatha mortar until an adequate particle size (0.25 mm) and weighed approximately 1 g.

X ray diffraction (XRD)

The analyses were carried out in the Scientific Instrument Service of the University of Granada using a diffractometer BRUKER D8 ADVANCE equipped with a copper tube, geometry θθ and with a LYNXEYE Detector. Diffraction data were collected in the range of 2θ Bragg angles from 5º to 80º in 0.02º steps, step time 0.2 s.

X-Ray Fluorescence

Mineral analysis of the container

Recommended sample quantity is 0.1 g. The sample is mixed with wax (as binder) and boric acid. This mixture is processed in the form of pellet (10 mm diameter) with the aid of a hand press and placed in an isolated chamber where a vacuum (%3C10 Pa) is made.

Wavelength Dispersive X-ray Fluorescence (WDXRF)

AXIOS Panalytical wavelength dispersive X-ray fluorescence (WD-XRF) spectrometer owned by the Center for Innovation and Technological Research in the University of Seville (CITIUS) (Figure 12). The main features of the device include: Rh anode (4.4 kW maximum power), 3 collimators (150 μm, 300 μm and 700 μm), 6 analyzer crystals (LIF200, LIF 220, PX-10, Ge111, PE002, PX-1) that allow qualitative and quantitative chemical analysis of elements from O to U in a wide range of concentrations (from main components to traces), a flow detector (for Z%3C29 elements) and a scintillation detector (for Z>29 elements).
