The Belluno Thrust between Monte Coppolo and Monte Agaro (Eastern Southern Alps, Northern Italy)
No full textThe Eastern Southern Alps are a southverging postcollisional thin skinned chain, which develop between Periadriatic
Lineament and Venetian Plain in Northern Italy. Four are the main thrusts building the chain: Marmolada, Valsugana,
Belluno and Bassano Thrusts. Marmolada is a pellicular structure involving Upper Permian-Middle Triassic succession;
Belluno represents the propagation of Valsugana indentation involving the crystalline basement intruded by Lower
Permian Cima d’Asta body; Bassano and Montello are the more recent foothills structures. All these thrusts are N90 to
N70 oriented, propagating southwards from Early Miocene to Recent (Castellarin et al., 2006). At M. Coppolo the
stratigraphic sequence includes the peritidal dolostones of Upper Triassic Dolomia Principale and the peritidal limestones
of Calcari Grigi Group. It includes M. Zugna Fm. with abundant chert nodules, defining a strong subtidal environment,
Loppio Oolite, Rotzo Fm. and Toarcian Grigno Oolite (Trevisani, 1991), very similar to Massone Oolite of Sarca Valley.
These oolitic bars mark the western and eastern border of Trento Platform during Lias. Aalenian encrinites of San Vigilio
Oolite, Middle-Upper Jurassic Rosso Ammonitico, Lower Cretaceous Maiolica and Upper Cretaceous Scaglia Rossa Fms
follow, marking the final drowing of Trento Platform causing pelagic conditions. The Belluno Thrust (BT), W-E oriented,
extends from Pieve Tesino to Caporetto bordering the northern margin of Belluno syncline (D’Alberto et al., 1995). BT
is highlighted by anticline of M. Coppolo–M. Agaro, involving the entire stratigraphic succession with the northern limb
gently dipping northwards (Brocon Pass) and the southern one vertical to overturned. The Belluno Thrust split into three
southverging structures from North to South: M. Piad Line, a steep deepening reverse fault cutting the M. Coppolo
Anticline hinge; Sasso Falares Line dipping 50° northwards along which the Coppolo Anticline thrusts over the Calcari
Grigi-Maiolica succession arranged in an another anticline representing the Sasso Falares-Val Nuvola Duplex (SFVND);
Belluno Line s.s. dipping 30° northwards, along which M. Zugna Fm. thrusts over Maiolica, bordering southwards the
SFVND. The shortening is about 5-6 km. A new outcrop of BT at Pugnai shows the architecture of thrust.

No full textTortonian-Pleistocenic oceanic features in the Southern Tyrrhenian Sea: magnetic inverse model of the Selli-Vavilov region
No full textWe show the magnetic model of the Selli-Vavilov region. The Selli Line is known as the northwestern edge of the southern Tyrrhenian basin. The tectonic evolution of the Tyrrhenian basin is dominated by a Tortonian - Quaternary extension through the eastward movement of the Apennine subduction system. This migration has generated a diffuse stretching of the continental crust with the emplacement of new oceanic material. This latter occurred in several localized zones where the eastward retreating of the Ionian subduction system produced a strong depletion of the crust with formation of basins and correlated spreading. Nowadays the presence of oceanic crust is confirmed through direct drilling investigation but a complete mapping of the oceanic crustal distribution is still lacking. The Selli-Vavilov region shows a differentiated crustal setting where seamount structures, the oceanic basement portions and continental crust blocks are superimposed. To this aim, a 2D inversion of the magnetic data of this region was conducted to define buried structures. The magnetic susceptibility pattern was computed by solving the least squares problem of the misfit between the predicted and real data for separated wavebands. This method produced two 2D models of the high and low frequency fields of the Selli-Vavilov region. The two apparent susceptibility maps provide different information for distinct ranges of depth. The results of the inversions were also combined with seismic data of the Selli region highlighting the position of the highly-magnetized buried bodies. The results confirm a role for the Selli Line as a deep crustal boundary dividing the Sardinian passive domain from the easternmost active region where different oceanic structures are located. The Selli Line has worked as a detachment fault system which has moved eastward. Finally, the Selli-Vavilov region may be interpreted as a tectonic result due to a passive asymmetrical rift occurred between the Tortonian and Pliocene.Published251-2662.6.

Complex Power Distribution Network Investigation Using SPICE Based Extraction from First Principle Formulations
No full textThe modeling and the analysis of the power distribution networks (PDN) within multi-layer printed circuit board is crucial for the investigation of the performance of PCB systems. Carrying out such analyses in SPICE based tools has the advantage of being faster than the corresponding full-wave modeling and it allows obtaining both frequency and time domain results
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
