Abstract

Team UNIPG from the University of Perugia in collaboration with SEG EVOLVE worked on the data set from the cooper basin finding the best investment opportunity for a possible reservoir of gas, taking into account geology, geophysics (seismic interpretation), volumetrics, and engineering along with a provision for CCUS. We would like to invite you to our short 30-minute presentation discussing all the details of our prospect.

Abstract

Ground motion is one of the main hazards facing the mining sector. Due to social pressure and in their own interest, mining companies are obliged to strictly control the stability of their facilities, especially with regard to tailings-dams and open pits. To improve the monitoring capacity, the ground-based instrumentation can be completed with satellite data for devising a more robust and safe monitoring system. Unfortunately, this monitoring integration is not the norm. Fortunately, this is changing rapidly thanks to, among others, the launching of the Sentinel-1 satellite (2014-15) that has rocked the InSAR world with its great features and its wide range of applications, even on an engineering scale. Another barrier that remains to normalize the use of Sentinel-1 data in the mining sector is the complex and heavy processing, which comes to require the use of powerful servers. Our project aims to break this barrier through an algorithm that automatically processes each new Sentinel-1 acquisition down to a user level. Our project partner is Aminer and the case studies are the Riotinto, Aznalcollar, Tharsis, and La Zarza mines, located in the Pyrite Belt.

Abstract

Permafrost, the permanently frozen ground, is warming due to global temperature rise. Permafrost research has progressed fast in the last decade, as large areas in the Polar Regions, in mountain environments and on high-altitude plateaus are experiencing accelerated environmental changes in response to thaw and permafrost degradation. Climate scenarios for the next decades project a reduced the extent of permafrost coverage and increasing ground temperatures, promoting changes in terrestrial and nearshore ecosystem dynamics. In this talk, we will examine the recent evolution of permafrost as well as the associated environmental changes.

Abstract

La Patagonia Austral muestra rasgos paisajísticos y topográficos muy particulares que los distinguen del resto del cinturón andino. Esta región ha sido afectada por la subducción de la Dorsal oceánica Sísmica de Chile la cual impulsó el desarrollo de una ventana astenosférica sobre la región. Ésta habría comenzado a subducir en el extremo más austral de Sudamérica a los ~17 Ma, y habría migrado hacia el Norte posicionándose en su ubicación actual a los 46.5°S. La evolución de la ventana astenosférica coincide con un periodo de inactividad tectónica cortical importante desde los 12Ma hasta la fecha. Sin embargo, la región muestra claras evidencias de alzamiento, exhumación y generación de relieve desde entonces. Tanto las áreas cordilleranas como la región extra-Andina habrían sido levantadas alrededor de 1 km. Hasta el día de hoy no existe consenso sobre el mecanismo generador de relieve sobre la región. El objetivo de esta investigación es avanzar en el conocimiento de la generación de topografía en los Andes patagónicos y dar luz sobre el vínculo existente entre el desarrollo topográfico y el desarrollo de ventanas astenosféricas.
