“…This system is composed of NW-SE to NNW-SSE trending, NE-dipping, high-angle faults buried beneath the Quaternary alluvial cover of the Veneto plain, and it bounds the northeastern part of the Adria Plate indenter to the west (Burrato et al 2008;Pola et al 2014b). The SVFS developed as a system of high-angle normal faults during Mesozoic and Paleogene, when it accommodated the extension affecting the passive margin of the Adria plate (Zampieri 1995;Masetti et al 2012). Subsequently, it was reactivated during the Neogene flexural cycles bending the Veneto plain (Fantoni et al 2002) and was mainly active during the last Pliocene-Quaternary flexural cycle, accommodating: i) the flexuring towards the south with a vertical scissor movement (Pola et al 2014b); and ii) the northward movement of the Adria Plate indenter (e.g.…”

The Euganean Geothermal Field (EGF) is the most important thermal field in northern Italy. It is located in the alluvial plain of the Veneto Region where approximately 17*10 6 m 3 of thermal water with temperatures of 60-86 °C are exploited annually. A regional-scale conceptual model of the Euganean Geothermal System is proposed in this paper using the available hydrogeologic, geochemical and structural data for both the EGF and central Veneto. The thermal water is of meteoric origin and infiltrates approximately 80 km to the north of the EGF in the Veneto Prealps. The water flows to the south in a Mesozoic limestone and dolomite reservoir reaching a depth of approximately 3,000 m and a temperature of approximately 100 °C due to the normal geothermal gradient. The regional Schio-Vicenza fault system and its highly permeable damage zone act as a preferential path for fluid migration in the subsurface. In the EGF area, a geologic structure formed by the interaction of different segments of the fault system increases the local fracturing and the permeability favoring the upwelling of the thermal waters. Numerical simulations are performed to validate the proposed conceptual model using a finite difference code that simulates thermal energy transport in hydrothermal systems. A specific configuration of thermal conductivity and permeability for the formations involved in the thermal system is obtained after calibration of these parameters. This set of parameters is verified in a long-term simulation (55,100 years) obtaining a 60-70 °C plume in the EGF area. The modeled temperatures approach the measured temperatures of 60-86 °C, demonstrating that this conceptual model can be realistically simulated.

“…As criteria for distinguishing the stratigraphic units of the Calcari Grigi Group, we used those adopted for the Mezzolombardo sheet [Avanzini et al, 2012]. Being beyond the scopes of this contribution, we do not report a complete description of the Calcari Grigi units and of their distinctive features, however detailed informations can be found in Masetti et al [1998] and Avanzini et al [2012]. LiDAR DTM obtained considering last-pulse laser signal were helpful in tracing faults and geologic boundaries in the areas covered by the vegetation.…”

“…The Calcari Grigi Group [Avanzini et al, 2006] encompasses the Early Jurassic sediments deposited on one of these highs. Rifting-induced synsedimentary tectonics in the area [Bertotti, 2001;Berra and Carminati, 2010] is testified by the presence of synsedimentary faults and structures and by sharp and abrupt thickness-variations in the Calcari Grigi Group's stratigraphic units [Masetti et al, 1998[Masetti et al, , 2012Franceschi et al, 2014a]. The study area is located close to Mezzolombardo village (Fig.…”

LiDAR and photogrammetry data are integrated to study an Early Jurassic extensional synsedimentary structure in the Italian Southern Alps. Airborne LiDAR data helped in getting geologic information in areas covered by vegetation, photogrammetry was applied to produce a high-resolution 3D textured model of the inaccessible parts of the outcrop. LiDAR and photgrammetric data were merged together producing a multi-resolution model. Key geologic boundaries and faults bounding the synsedimentary structure were digitized in a 3D geomodeling environment. The reconstruction yielded information about the structure kinematics and accumulated displacements.

“…The Jurassic succession of the Trento Platform is divided into two main stratigraphic sequences, the shallow marine Calcari Grigi-Oolite di San Vigilio Groups (Hettangian-Pliensbachian) and the pelagic Rosso Ammonitico Veronese (upper Bajocian-Tithonian) (Barbieri and Grandesso 2007;Masetti et al 2012). The Calcari Grigi Group (former Calcari Grigi Formation; Bosellini and Broglio Loriga 1971) is divided into three units, the Monte Zugna Formation (HettangianSinemurian), the Loppio Oolitic Limestone (SinemurianPliensbachian) and the Rotzo Formation (Pliensbachian) (Castellarin et al 2005;Masetti et al 2012).…”

The Rotzo Formation is famous for its Lower Jurassic terrestrial flora and marine (invertebrate) and terrestrial (dinosaur footprint) fauna. However, lycophyte macrofossils were never described from this time period in Italy, although palynological analyses yielded abundant lycophyte spores. Dispersed megaspores, in association with charcoal and amber drops, were recently collected from several horizons and outcrops of the Monte Lessini area. Sedimentological and palaeontological data reconstruct the palaeoenvironment as a paralic swamp under a warm and humid (monsoonal) climate. This is the first record of Jurassic megaspores from Italy, increasing our understanding of Jurassic lycophyte diversity, since at least five microspore and five megaspore genera with selaginellalean botanical affinities can be distinguished. Moreover, this underlines how well these brackish environments were adapted for the preservation of fossil plant remains (including amber).
