| 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). Introduction to supergene residual deposits (Ni, Al) | |||||||||||||||||||||||||||||||||||
| Learning objective | Understanding the fundamental processes of hydrothermal, magmatic and supergene ore formation, recognising and interpreting mineralised rocks in geological context | |||||||||||||||||||||||||||||||||||
