Laboratory of Geochemistry - LGCH

LOCATION: Palazzo delle Scienze, Ground Floor, Rooms T-6 and T-12

BRIEF DESCRIPTION:

The research activities of the Laboratory of Geochemistry focus on the following topics: i) ab initio quantum-mechanical calculations, atomistic simulation and computational modelling of the chemico-physical and thermodynamic properties of minerals and crystalline solids, glasses, silicate melts, aqueous solutions, geothermal fluids and volcanic gases; ii) numerical simulation of water-rock interaction processes and relevant geological implications; iii) 3D modelling of transport phenomena of potentially ecotoxic elements and pollutants in different environments (e.g. waste dumps, harbour areas, etc.) ; iv) geochemical mapping via in-situ measurement and numerical modelling of environmental chemico-physical parameters.  

The acquired, designed or self-produced instrumentation is used to assess, simulate and process in real time the dynamics of geological systems with a high bio-geochemical reactivity, such as rocks and minerals, stream sediments, surface water, groundwater, seawater, silicate melts and endogenous gases (natural or anthropic, like CO2 and methane).

The members of LGCH contribute also to the preservation, management and development of the historical and modern mineralogical collections at DISTAV.

TEACHING ACTIVITIES:

The equipment and computational resources of the Laboratory of Geochemistry are employed to support several research, teaching and fieldwork activities provided by the Research Group (courses of Geochemistry, Hydrogeochemistry, Volcanology and Geostatistics for Natural Resources).

The laboratory instrumentation is also widely used during national and international PhD schools and workshops organized by our Research Group in collaboration with other Universities, Research Institutions (e.g. INGV, CNR, ENEA) and Scientific Societies (SoGeI, SIMP, etc.) to promote the discipline.
