Periodicityyearly recurring course
Language of instructionEnglish
CommentCan be chosen as an elective course within the Bachelor. Prospective MSc-Students attending the module "Mineral Resources" should attend Ore Deposits I and II in the first year of their MSc studies.


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.
