The Predazzo Intrusive Complex (PIC), a Ladinian plutonic body located in the Southern 31 Alps (NE Italy), is made up of a 4.5 km 3 gabbroic to syenitic and syenogranitic intrusion, 32 basaltic to latitic volcanic products (about 6 km 3 in volume) and by an extended dike swarm 33 intruding both intrusive and volcanic rocks. An extensive field survey of the complex, 34 followed by detailed petrographic and geochemical analyses, allowed the identification of 35 three different magmatic units: a Shoshonitic Silica Saturated Unit (SS), 3.1 km 3 in volume, a 36 Shoshonitic Silica Undersaturated Unit (SU), 0.3 km 3 in volume, and a Granitic Unit (GU), 37 1.1 km 3 in volume. K-affinity, marked Nb and Ti negative anomalies and a strong Pb 38 enrichment are distinctive markers for all PIC lithotypes. A general HFSE (Th, U, Pb), LREE 39 (La, Ce, Pr, Nd) and Na enrichment characterises the SU suite with respect to the SS series. 40 Mass balance calculations, based on major and trace element whole rock and mineral 41 compositions, have been used to simulate the fractionation process of SS and SU suites, 42showing (i) the complexity of the evolutionary stages of the PIC and (ii) the analogy between 43 the calculated subtracted solid assemblages and the natural cumulitic lithotypes outcropping 44 in the area. The field relationships between the various portions of the intrusive complex, the 45 volcanic products and the dike swarm define the temporal evolution of the PIC, in which the 46 SS magma batch was followed by the GU and later on by the SU intrusion. The presence, in 47 both eastern and western portions of the complex, of a transitional magmatic contact between 48 the intrusive rocks of the SS suite and the volcanics is not in favour of the hypothesis of a 49 caldera collapse to explain the ring-like shape of the PIC.

The renowned Vitis vinifera L. cultivar "Glera" (Magnoliopsida Vitaceae) has been grown for hundreds of years in the Italian regions of Veneto and Friuli to produce the sparkling Prosecco wine, with controlled designation of origin (DOC). We evaluated the relationship among the concentrations of rare earth elements (REE) in soil and in "Glera" grape berries in vineyards belonging to five different localities in the Veneto alluvial plain, all included in the DOC area of Prosecco. The concentration of REE in samples of soil and juice or solid residues of grape berries was determined by inductively coupled plasma mass spectrometry (ICP-MS), and the index of bioaccumulation was calculated to define the specific assimilation of these elements from soil to grape berries. The concentration of REE in soil samples allowed an identification of each locality examined, and REE were mostly detected in solid grape berry residues in comparison to juice. These data may be useful to associate REE distribution in soil and grape berries to a specific geographical origin, in order to prevent fraudulent use of wine denomination labels.
