| 651-4037-00L | Ore Deposits I Can 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. | 3 credits | 2G | C. Chelle-Michou, O. Laurent | |
| Abstract | Principles 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). | ||||
| Learning objective | Understanding 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. | ||||
| Lecture notes | Notes handed out during lectures | ||||
| Literature | Extensive literature list distributed in course | ||||
| Prerequisites / Notice | 2 contact hours per lecture / week including lectures, exercises and practical study of samples, and small literature-based student presentations. Supplementary contact for sample practicals and exercises as required. Credits and mark based on participation in course (exercises, 50%) and 1h written exam in the last lecture of the semester (50%). | ||||
| 651-4082-00L | Fluids and Mineral Deposits The course will no longer be published in the course catalogue after autumn semester 2019. It will run as will be a group seminar starting spring semester 2020. | 2 credits | 1S | T. Driesner, C. Chelle-Michou, B. Lamy-Chappuis, O. Laurent | |
| Abstract | Presentations and literature discussions on current research topics in crustal fluids and mineral resources research. | ||||
| Learning objective | Provide 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. | ||||
| Content | Themen zur Hydrothermalgeochemie, Modellierung von Fluidprozessen, Mikroananlytik, Isotopen-Tracing von hydrothermalen Transportprozessen und der Bildung von Erzlagertätten | ||||
| Prerequisites / Notice | Register in MyStudies and send mail to michael.schirra@erdw.ethz.ch, to be placed on distributor for the irregular program | ||||
