IGNEOUS PROCESSES. 1. IGNEOUS ORE-FORMING PROCESSES. 1.1. Introduction -- 1.2. Magmas and metallogeny -- 1.3. Why are some magmas more fertile than others? The “inheritance factor” -- 1.4. Partial melting and crystal fractionation as ore-forming processes -- 1.5. Liquid immiscibility as an ore-forming process -- 1.6. A more detailed consideration of mineralization processes in mafic magmas -- 1.7. A model for mineralization in layered mafic intrusions -- 2. MAGMATIC-HYDROTHERMAL ORE-FORMING PROCESSES. 2.1. Introduction -- 2.2. Some physical and chemical properties of water -- 2.3 Formation of a magmatic aqueous phase -- 2.4. The composition and characteristics of magmatichydrothermal solutions -- 2.5. A note on pegmatites and their significance to granite-related ore-forming processes -- 2.6. Fluid–melt trace element partitioning -- 2.7. Water content and depth of emplacement of granites – relationships to ore-forming processes -- 2.8. Models for the formation of porphyry-type Cu, Mo, and W deposits -- 2.9. Fluid flow in and around granite plutons -- 2.10. Skarn deposits -- 2.11. Near-surface magmatichydrothermal processes – the “epithermal” family of Au–Ag–(Cu) deposits -- 2.12. The role of hydrothermal fluids in mineralized mafic rocks -- PART 2. HYDROTHERMAL PROCESSES. 3. HYDROTHERMAL ORE-FORMING PROCESSES. 3.1. Introduction -- 3.2. Other fluids in the Earth’s crust and their origins -- 3.3 The movement of hydrothermal fluids in the Earth’s crust -- 3.4. Further factors affecting metal solubility -- 3.5. Precipitation mechanisms for metals in solution -- 3.6. More on fluid/rock interaction – an introduction to hydrothermal alteration -- 3.7. Metal zoning and paragenetic sequence -- 3.8. Modern analogues of ore-forming processes – the VMS–SEDEX continuum -- 3.9. Mineral deposits associated with aqueo-carbonic metamorphic fluids -- 3.10. Ore deposits associated with connate fluids -- 3.11. Ore deposits associated with near surface meteoric fluids (groundwater) -- PART 3. SEDIMENTARY/ SURFICIAL PROCESSES. 4. SURFICIAL AND SUPERGENE ORE-FORMING PROCESSES. 4.1. Introduction -- 4.2. Principles of chemical weathering -- 4.3 Lateritic deposits -- 4.4. Clay deposits -- 4.5. Calcrete-hosted deposits -- 4.6 Supergene enrichment of Cu and other metals in near surface deposits -- 5. SEDIMENTARY ORE-FORMING PROCESSES. 5.1. Introduction -- 5.2. Clastic sedimentation and heavy mineral concentration – placer deposits -- 5.3. Chemical sedimentation – banded iron-formations, phosphorites, and evaporites -- 5.4. Fossil fuels – oil/gas formation and coalification -- PART 4. GLOBAL TECTONICS AND METALLOGENY. 6. ORE DEPOSITS IN A GLOBAL TECTONIC CONTEXT. 6.1. Introduction -- 6.2. Patterns in the distribution of mineral deposits -- 6.3. Continental growth rates -- 6.4. Crustal evolution and metallogenesis -- 6.5. Metallogeny through time -- 6.6. Plate tectonics and ore deposits – a summary.
