I graduated in Earth Sciences at the University of Padova in 1987, became lecturer at the same University in 1990 and associate professor in Petrology and Petrography in December 2002. My teaching activity presently includes: Petrographic Microscopy and Field Geology for the Course in Earth Sciences

characterization, restoration and conservation of mural paintings. However, objective criteria
to identify the two main lime-based painting techniques, fresco and lime-paint, have not yet
been systematically verified on replicas. Replicas were painted following both fresco and
lime-painting techniques. A comparison of microstratigraphic sequences and distribution of
chemical elements reveals systematic differences between the two techniques, providing objective
distinguishing criteria. Samples from the Abbey of Chiaravalle (Milan, Italy) and Pompeii
were also analysed, and the results were compared with experimental data to validate the
recommended criteria.

Particularly as regards pore-size distribution and the interconnection model, porosity is an important parameter to evaluate and predict the durability of bricks. The pore system is in fact the main element, which correlates building materials and their environment (especially in cases of aggressive weathering, e.g., salt crystallisation and freeze-thaw cycles) and determines their durability. Four industrial bricks with differing compositions and firing temperatures were analysed with " direct " and " indirect " techniques, traditional methods (mercury intrusion porosimetry, hydric tests, nitrogen adsorption) and new analytical approaches based on digital image reconstruction of 2D and 3D models (back-scattered electrons and computerised X-ray micro-Tomography, respectively). The comparison of results from different analytical methods in the " overlapping ranges " of porosity and the careful reconstruction of a cumulative curve, allowed overcoming their specific limitations and achieving better knowledge on the pore system of bricks.

The two new minerals roggianite (PASSAGLIA, 1969) and vigezzite (GRAESER et al., 1979) were first described in the Alpe Rosso pegmatite. Emerald gems, feasible to be faceted up to one carat, were found in the Pizzo Marcio northern pegmatite (BOSCARDIN et al., 1976). These pegmatites occur in the Southern root portion of the Alpine Penninic nappe and are hosted by amphibolite-grade metamorphic rocks (Fig.1). They show sensible enrichment in high field strength elements (HFSE) and they cross-cut metaperidotite-serpentinoschists interpreted as metaophiolites strips (REINHARDT, 1966). The Pizzo Marcio-Alpe Rosso albitized pegmatites belong to an extended pegmatite field several tens of kilometres in length occurring along the Insubric Line, a ...

Ceramic production in the Final Bronze Age was characterised by the use of grog, as in other coeval sites of the southern Adige and eastern Po plains. From the beginning of the Iron Age, the number of recipes increased considerably, the use of grog gradually decreased, and cases of importation are also attested. These changes were probably due to increasing socio-economic complexity and the introduction of new production techniques.
