3 credits2GC. A. Heinrich, O. Laurent
AbstractPrinciples of hydrothermal ore formation, using base metal deposits (Cu, Pb, Zn) in sedimentary basins to explain the interplay of geological, chemical and physical factors from global scale to sample scale. Introduction to orthomagmatic ore formation (mostly Cr, Ni, PGE).
ObjectiveUnderstanding the fundamental processes of hydrothermal and magmatic ore formation, recognising and interpreting mineralised rocks in geological context
Content(a) Principles of hydrothermal ore formation: base metal deposits in sedimentary basins. Practical classification of sample suites by genetic ore deposit types
Mineral solubility and ore deposition, principles& thermodynamic prediction using activity diagrams. Stable isotopes in ore-forming hydrothermal systems (O, H, C, S) Driving forces and structural focussing of hydrothermal fluid flow

(b) Introduction to orthomagmatic ore formation. Chromite, Ni-Cu sulphides and PGE in layered mafic intrusions. Distribution coefficients between silicate and sulphide melts. Carbonatites and pegmatite deposits.

AbstractPresentations and literature discussions on current research topics in crustal fluids and mineral resources research.
ObjectiveProvide a deeper understanding in the selected research fields on hydrothermal processes and ore deposit formation. This is achieved by literature work as well as discussions of current BSc, MSc and PhD projects at the institute.
ContentThemen zur Hydrothermalgeochemie, Modellierung von Fluidprozessen, Mikroananlytik, Isotopen-Tracing von hydrothermalen Transportprozessen und der Bildung von Erzlagertätten
