“…In the same period, Euganean trachytic millstones and rotary-millstones were manufactured and spread throughout the X Regio Augustea, Venetia et Histria Antonelli and Lazzarini work in progress) also reaching some localities of ancient Aemilia and Picenum (Marche) regiones (i.e., Fossombrone and Urbisaglia e Renzulli et al, 2002a;Santi and Renzulli, 2006). Among the 70 open-pit trachyte quarries identified in the field by Capedri et al (2000), the sites where exploiting activity was particularly important were Monselice, Monte Rosso, Monte Oliveto, Monte Merlo, Monte Lispida, Monte Alto and Monte Altore (Fig. 2).…”

“…5a) these rocks are principally transitional trachytes, seldom rhyolites or trachyandesites. Capedri et al (2000) outlined mineralogicalpetrographic, and chemical parameters characterising the trachytes of the most important historical quarries of the district. From a compositional and textural point of view Euganean trachytes are always porphyritic lavas (PI mainly from 20 vol.…”

“…lavas from the Monselice and Monte Oliveto areas) as well as no fluidal orientation (felty texture; e.g. trachytes from Monte Cero, Monte Altore, Monte Rosso, Monte Merlo, Monte Lispida and many other areas; Capedri et al, 2000); small amounts of interstitial quartz and, occasionally, minute interstitial brownish glass may also be present in the groundmass. It is very common to see grey-black inclusions with porphyric/granitoid/very weakly schistous fabric normally referring to trachyandesitic, gabbroic and cornubianitic composition, respectively (Lazzarini et al, 2008 and reference therein), that contain a larger amount of biotite, amphibole, pyroxene and magnetite than ordinary trachyte, and sometimes small amounts of calcite; more rare are white-gray xenoliths of alkaline-rhyolites or granitoid rocks.…”

“…As described by Capedri et al (2000), trachytes of individual quarrying areas are chemically quite homogeneous, but there is a rather wide chemical variability among the different sites, which allows a good differentiation within the main Roman sources. The authors consider TiO 2 , Zr, Th, Nb, Y, V, Rb, Sr and Pb particularly useful for discriminating and propose some valuable binary plots able to reduce all the main quarried trachytes to five fields (Th vs Sr; Fig.…”

Geophysical prospection on 14 ha integrates the processing and interpretation of vertical multispectral and oblique\ud aerial images for uncovering the archaeology of the Roman city of Altinum. This Iron Age and Roman harbour city\ud was completely abandoned in the early Middle Ages, when people moved to nearby lagoon islands, and so the site\ud is particularly fit for the application of non-invasive techniques. Primary aims of the research were to test the interpretation\ud of archaeological structures in the city centre, estimate their degree of preservation in the subsoil, and update\ud previous knowledge on the urban landscape. Target areas were identified first through remote sensing with later\ud magnetic gradiometer mapping of the consular road (via Annia) and its adjoining streets, foundations of large buildings,\ud theatres, temple and forum, a main canal with possible boatyard/storing place and workshops. Multi-electrode\ud automatic resistivity profile produced a very detailed survey of the little theatre (odeon) and basilica. The groundpenetrating\ud radar traced the city walls, while frequency-domain electromagnetics mapped the street pattern.\ud Buried archaeological structures were located with an estimated error < 0.5 m. Floors and foundations of Roman\ud buildings and infrastructures appear to be preserved between 0.5 and 2 m depth. They probably relate to a reorganization\ud of the city, which occurred between the second half of the second century and the end of the first century\ud BC, having via Annia and the forum as the main city axis, and incorporating few elements of the Iron Age settlement,\ud such as the canal and city boundary. Eight city districts could be recognized, each one showing prevalent public,\ud residential and other productive functions. In the ancient past the monumental buildings of the city were potentially\ud visible from ships in the Adriatic Sea, and could act as nautical signals of the entrance to the lagoon along this low\ud and otherwise monotonous coast.

New petrographic and geochemical tracers for recognizing the provenance quarry of trachyte of the Euganean Hills, northeastern Italy

et al. 2017

Trachyte of the Euganean Hills is a subvolcanic porphyritic rock historically used as carving and building stone in northern and central Italy–primarily from Roman times onward–with the first evidence of its use dating back to prehistory. The numerous quarries and very similar trachyte varieties, as well as thewidespread use of this stone, create several problems in defining its provenance for archaeological and historical materials. New petrographic and geochemical tracers for recognizing the provenance quarry of Euganean trachyte are presented here, providing a Comprehensive reference database for archaeometric studies. The petrographic markers principally include quantitative data on mineralogical composition and textural features of phenocrysts and groundmass, determined by image analysis of chemical maps acquired by micro X-ray fluorescence and scanning electron microscope-energy-dispersive X-ray spectroscopy; particular use has been made of data on the abundance and grain-size distribution of feldspar phenocrysts, phenocrysts-groundmass ratio, content of SiO2 phases in the groundmass, and the arrangement and grain-size of microlites in the matrix. The geochemical tracers involve composition of bulk rock and phenocrysts, determined by X-ray fluorescence and laser ablation inductively coupled plasma mass spectrometry, respectively; quarry recognition can be achieved using plots built from concentrations of major and trace elements, with mineral-scale chemistry being the most effective and precise discriminant property, especially in the case of biotite and, secondarily, augite, kaersutite, and magnetite
