Production of hybrid granitic magma at the advancing front of basaltic underplating: Inferences from the Sesia Magmatic System (south-western Alps, Italy)

Autor: Urs Klötzli, J. E. Quick, Gabriella Demarchi, Silvano Sinigoi

Publikováno v: Lithos. :109-122

The Permian Sesia Magmatic System of the southwestern Alps displays the plumbing system beneath a Permian caldera, including a deep crustal gabbroic complex, upper crustal granite plutons and a bimodal volcanic field dominated by rhyolitic tuff filli

Highly radiogenic Sr-isotopic signature and trace element content of grape musts from northern Piedmont vineyards (Italy)

Autor: Antonella Buccianti, Lisa Ghezzi, Ilenia Arienzo, Gabriella Demarchi, Riccardo Petrini

The analysis of trace metals and metalloids, and the Sr-isotopic systematics were applied to 16 must samples from vines growing in the Sesia Val Grande Supervolcano UNESCO Global Geopark in the northern Piedmont Region (Italy), a land worldwide famou

Structure and petrography of the Valle Mosso pluton, Sesia Magmatic System, Southern Alps

Autor: Giovanni Musumeci, L. Tavazzani, S. Peres, Gabriella Demarchi, Silvano Sinigoi

Publikováno v: Journal of Maps, Vol 13, Iss 2, Pp 684-697 (2017)

The Valle Mosso pluton (VMP) is a Permian granitic body intruded at intermediate to upper crustal levels in the rocks of the pre-Alpine basement of the Ivrea-Verbano Zone and Serie dei Laghi shortly after the end of Variscan orogeny. As a consequence

A model for thermal rejuvenation and eruption of a granitic magma chamber, Valle Mosso pluton, Sesia Magmatic System (Southern Alps, Italy)

Autor: Lorenzo Tavazzani, Stefano Peres, Silvano Sinigoi, Gabriella Demarchi, James E. Quick, Rita C. Economos, Urs Klötzli

Construction of granitic magma chambers is recognized as a pivotal intermediate stage in the ascent of silicic magmas (SiO in excess of 65 wt%) through continental crust. However, the mechanisms by which large volumes (> 100 km ) of these highly crys

Pressure Gradient and Original Orientation of A Lower‐Crustal Intrusion in the Ivrea‐Verbano Zone, Northern Italy

Autor: James E. Quick, Silvano Sinigoi, Adriano Mayer, Gabriella Demarchi

Publikováno v: The Journal of Geology. 106:609-622

The southern Ivrea‐Verbano Zone of the western Italian Alps contains a huge complex of mafic to intermediate plutonic rocks that intruded the lower continental crust during the Permian. Recent geologic mapping of the complex has characterized the e

Duration of igneous activity in the Sesia Magmatic System and implications for high-temperature metamorphism in the Ivrea–Verbano deep crust

Autor: Urs Klötzli, Gabriella Demarchi, Kei Sato, Colombo Celso Gaeta Tassinari, Zekerias Günes, James E. Quick, Silvano Sinigoi

Advection of heat by the intrusion of mantle-derived magma is frequently invoked as the driver of high-temperature metamorphic events in the deep crust. One of the best places worldwide to study and evaluate this process is the deep crustal section o

The Sesia Magmatic System

Autor: Gabriella Demarchi, G. Peressini, James E. Quick, Silvano Sinigoi

Publikováno v: Journal of the Virtual Explorer. 36

The Ivrea-Verbano Zone (IVZ) and Serie dei Laghi (SdL) of northwest Italy, are two lithostratigraphic units that constitute the deep- and the middle- to upper-crustal components, respectively, of a tilted and exposed section through the pre-Alpine cr

Mineral chemistry and Nd isotopic composition of two anorthositic rocks from the Kunene complex (South Western Angola)

Autor: Eduardo Morais, Francesca Federica Slejko, Gabriella Demarchi

Two anorthositic rocks from the Kunene complex (South Western Angola) were analyzed for their mineral compositions, major element chemistry and Nd isotopes. The two rocks were sampled from the northern and southern parts of the complex with respect t
