Characterization and study of the provenance of ceramics using portable X-ray fluorescence (pXRF): test study on terrae with granitic and metamorphic components from Castellar - Pendimoun (Impressa and Cardial, 6th millennium BCE)

SD1. Description of sampling contexts.
SD2. Location of « granitic » alteration earths sampled in the Argentera-Mercantour massif and piedmont (geological map 1/50 000, BRGM, sheet n°1579).
SD3. Location of « granitic » alteration earths sampled in the Maures massif (geological map 1/50 000, BRGM, sheet n°1359).
SD4. Location of glauconitic marls and earths sampled in the Orméa piedmont (geological map 1/50 000, BRGM, sheet n°1579).
SD5. Location of « granitic » alteration earths sampled in the Tanneron massif (geological map 1/50 000, BRGM, sheet n°1359).
SD6. Portable XRF analyses of CRMs, TIs heated to 700°C and ceramics from the CIMO program, processed during the two sessions in February and July 2019.
SD7. Means and standard deviations of portable XRF analyses of CRMs and CIMO ceramics (February and July 2019).
SD8. Elements identified by ICP-AES and ICP-MS in geological reference samples (raw and experimentally fired) and archaeological samples.
SD9. SiO2/Al2O3 vs Fe2O3 diagram allowing to distinguish the terrae coming from the Col de l'Orme, without removing the existing confusions between the three other "terrae of interest" (cf. figure 4).
SD10. Harker diagram for some chemical elements allowing to characterise the "terrae of interest" of the CIMO program. The SiO2 vs. CaO or Zr vs. Nb diagrams are the most discriminating in addition to the SiO2 vs. Al2O3 diagram (figure 4A).
SD11. Chemical elements normalized to the continental crust. Some elements (Al, Ca, Nb, Zr) appear to be discriminating, but the figure highlights the difficulty in distinguishing between the different "terrae of interest", visible in Figure 4 or in SD.3 and 4.
SD12. Variation of SiO2 and Al2O3 concentration of fired shards compared to the same non-fired shards (samples AP_018 and AP_049).
