| Abstract: | This paper presents the results of the archaeometric study of 30 grinding tools found in the Karst plateau (an area that spreads from the northeastern border of Italy to Slovenia) and in the Istria peninsula (Croatia). The petrographic and geochemical characteristics of the artefacts indicate that most of them would be made of trachytic volcanites extracted from the Euganean Hills, near Padua (Veneto). It is known that trachytic rocks from this area had been widely exploited in northern Italy during protohistoric times, but these data considerably enlarge the area of diffusion of saddle‐querns made of these rocks, extending it to Istria. Additionally, the likely provenance from Mount Etna of few other pieces of mugearites and hawaiites represents a new element, to be fully evaluated in the context of trans‐Adriatic exchange/trade connections. Analytical data and possible archaeological inferences are presented in detail in the text. |
