“…Major and trace elements in the soil samples were measured at the facilities of the Geological Survey of Japan (GSJ), part of the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, using a method developed by the GSJ. The method consisted of preparing high-dilution-ratio fused glass beads for the X-ray fluorescence (XRF) determination of major element oxides (Ejima et al 2018) and using the same beads for trace element measurements by femtosecond ultraviolet laser ablation ICP-MS (LA-ICP-MS) (Kon and Hirata 2015).…”

Olive oil traceability based on the intrinsic chemical composition of the oil is becoming increasingly important due to the prevalence of fraudulent geographical labelling of olive oils. For a traceability tool to be valid, it should be based on olive oil properties that are clearly related to provenance factors. However, multielement analysis of the oil has been used as a traceability tool without any proof of a direct link between the multielemental composition and the geographical origin of the oil. In order to verify this link, Tunisian olive terroir components from the 11 major olive-producing regions were sampled to evaluate the influences of these components (especially soil and climate) on the geochemical composition of Tunisian olive oil. Overall, geochemical processes relating to strontium and rare-earth element (REE) enrichment were found to control the multelemental compositions of Tunisian soils. Even though olive oils from the 11 Tunisian olive-growing regions considered did not strongly reflect the geochemical signatures of the corresponding Tunisian soils, the concentrations of four elements in the oils, namely Fe, Ti, Ni and Ba, showed significant positive Spearman correlations with their concentrations in the bioavailable extracts from those soils. Moreover, there were numerous significant correlations of elements in the olive oil with soil chemical and climate parameters. Our results clearly confirm that the complex interactions of the olives with the climate and soil chemistry during cultivation significantly affect the multielemental composition of the resulting olive oil. This finding implies that the elemental profile of the olive oil is an effective and valid marker of the geographical origin of the oil, as it is significantly linked to oil provenance factors. It also explains the discrepancies between the geochemical signature of an oil and that of the soil in which the olives were grown, as climate parameters affect the transfer of that signature from soil to olives. This work therefore provides the basis for a scientifically based approach to olive oil traceability. The results of this work can be utilized by agricultural authorities to realise the multielement-based traceability of olive oils from various Tunisian regions. Graphic abstract

All the granitoids in the Japanese Islands are Phanerozoic and of arc-type. They are part of the Late Mesozoic Circum-Pacific granite superprovince. Most of the Japanese granitoids were formed when the Japanese Islands belonged to the Eurasian continent, as the growing front of the continent. They are mostly of I-type, and S-type granitoids are very small in amount. The origin of these granitoids is mostly partial melt of mantle-derived mafic lower crust of arc without an involvement of ancient cratons or their derivatives.The granitic magmatism was quite episodic. % of their surface exposure area is occupied with -Ma, Paleogene to Cretaceous granitoids. In Southwest Japan, they constitute three arc-parallel granitic provinces called Ryoke, San-yo and San-in belts. A transect from the Ryoke to San-yo belt represents the hypothetical crustal cross section of the Cretaceous Eurasian continental margin. The Hidaka belt in Hokkaido is another example of a crustal cross section, exposing the deep Kuril arc at Miocene. On the fore-arc side of the Southwest Japan, -Ma, Middle Miocene granitic rocks are exposed sporadically but widely. The magmatism was very short-lived, supposed to be generated in an unusual tectonic setting related to back-arc opening and incipient subduction of the Philippine Sea plate. Middle Miocene and still younger granitoids are exposed in the Izu Collision Zone. The Quaternary granitoids of ~ Ma are exposed at the Central Highlands in central Japan. Jurassic and Triassic granitoids occur in the Hida belt, which is the most back-arc side unit of the Japanese Islands. Paleozoic granitoids are rare. They are exposed as geologically isolated small bodies or tectonic blocks.
