Lay Summary (English)

Lead
Lay summary
Natural deposits of economically important metals such as Cu, Mo, Pb, Zn and Au are formed by hydrothermal fluids (hot water-rich solutions and gases) circulating through the Earths crust, commonly in the subsurface parts of large ancient volcanoes that were later exposed by erosion, or at magmatically active mid-ocean ridges. Our group investigates the geological processes leading to such metal enrichments, as a long-term basis for predicting the location and composition of still undiscovered resources. This in turn contributes to basic knowledge required to ensure our future supply of essential mineral resources.
Our research involves a closely coordinated combination of four major approaches of investigation,:
- Field-based geological mapping, mainly in SE Europe and Argentina, to understand the large-scale spatial and temporal relationship between mineral deposits, tectonic deformation and magmatism
- Geochronological age dating to quantify the time sequence and duration of ore-forming processes
- Development of microanalytical techniques to measure the chemical and isotopic composition of microscopic inclusions of the original metal-transporting fluids enclosed inside minerals
- The development of computer methods to numerically simulate the flow of fluids though rocks, in order to integrate the observations about space, time and chemistry into quantitative dynamic models for the ore-forming process.
The 2004-2007 funding period of this ongoing project supports three PhD students working at ETH Zürich, but also includes a small contribution to collaborators in Bulgaria and Romania, who are essential for geological data access and who benefit in turn from our development of new analytical methods. To support own complementary research by these collaborators, we are leading a concurrent SCOPES project (see nr. IB7320-111130).
