Seminar - The “complex” electrical conductivity of ice and frozen ground

Speaker: Dr. Dr. Adrian Flores-Orozco (Department of Geodesy and Geoinformation, Technical University of Wien - Austria) | Thursday, November, 23, 2023 – 4.30 PM | Arduino Classroom

23.11.2023

This Seminar will revise ongoing approaches in the investigation of alpine permafrost using geophysical electrical methods and demonstrate the importance of accounting for interfacial conductivity in the case of frozen ground, as presented in Figure 1. Moreover, the seminar will present some of our recent results regarding the application of transient electromagnetic soundings to delineate ice‐rich areas in alpine permafrost. To this end, we propose a stochastic modeling and inversion approach explicitly considering interfacial conductivity that permits us to evaluate the uncertainty of the resulting model parameters.

Seminar - Le deformazioni da carico idraulico sull’Altopiano del Cansiglio: storia di una ricerca multidisciplinare

Speaker: Dr. Barbara Grillo (Dip. Matematica e Geoscienze Università di Trieste; SpeleoTeam Conegliano CAI) | Thursday, November, 16, 2023 – 4.30 PM | Arduino Classroom

16.11.2023

La correlazione tra il monitoraggio idrogeologico e geofisico ha evidenziato la presenza di deformazioni del massiccio del Cansiglio indotte dal carico idraulico. Durante eventi di piogge intense si osservano rapide deformazioni registrate sia dai pendoli sia dai rilievi GPS, e deformazioni stagionali evidenziati dai GPS. L’Altopiano del Cansiglio fa parte di una notevole idrostruttura elastica non omogenea che si muove con un sistema di drenaggio diretto in direzione del complesso sorgentifero di Polcenigo-Caneva che alimenta anche il Fiume Livenza. Oltre al deflusso verso SE, le informazioni che vengono dai clinometri indicano anche tutti gli episodi di carico e scarico impulsive, confermati ora anche dal monitoraggio delle acque nel sifone. La ricerca si avvale della collaborazione dell’Istituto Nazionale di Geofisica e Vulcanologia di Roma e dei gruppi speleologici locali.

Seminar - Ancient impacts, early life, and gemstones: Insights into the Archean Eon from southern West Greenland

Speaker: Dr. Chris Yakymchuk - Waterloo University (Canada) | Thursday, November, 9, 2023 – 4.30 PM | Arduino Classroom

09.11.2023

The Akia Terrane of southern West Greenland hosts several peculiar geological features that record a transitional period in global geodynamics during the Archean Eon. The terrane is dominated by grey gneisses, metasedimentary rocks, and ultramafic complexes metamorphosed to granulite‐facies conditions. In the northern Akia Terrane, microstructures and structural map patterns have been used to argue that the ~100 km wide Maniitsoq structure formed from a giant meteorite impact at 3.0 Ga; however, diagnostic evidence of impact metamorphism is absent.

Seminar - A multiscale approach to fluid-rock interaction processes from Earth’s depth to the surface

Speaker: Dr. Tommaso Tacchetto - Curtin University (Australia) | Thursday, October, 26, 2023 – 4.30 PM | Arduino Classroom

26.10.2023

In this seminar, it will be shown how the application of a suite of cutting‐edge techniques can allow us to enhance our understanding of the nanoscale manifestation of fluid‐rock interactions and their consequences for larger‐scale dynamics. The analytical workflow is applied to type localities of deep crust fluid‐melt‐rock interaction and weathering patterns of the World’s largest sites of human heritage.
