This third edition of A.M. Evan's successful undergraduate text Introduction to Ore Geology is an enlarged and extensively revised work. The increase in size (and the new title) primarily reflects the additional coverage of industrial minerals and bulk materials, an area of economic geology that has grown in prominence over the past decade. The new edition includes three new chapters: the opening chapter provides an overview of mineral economics and two chapters are devoted entirely to industrial minerals. Part 1: Principles - Some Elementary Aspects of Mineral Economics. · The Nature and Morphology of the Principal Types of ore Deposit. · Textures and Structures of Ore and Gangue Minerals. · Fluid Inclusions. · Wall Rock Alteration. · Some Major Theories of Ore Genesis. · Geothermometry, Geobarometry, Paragenetic Sequence, Zoning and Dating of Ore Deposits. Part 2: Examples of the More Important Types of Ore Deposit - Classification of Ore Deposits. · Diamond Deposits in Kimberlites and Lamproites. · The Carbonatite-alkaline Igneous Ore Environment. · The Pegmatitic Environment. · Orthomagmatic Deposits of Chromium, Platinum, Titanium and Iron Associated with Basic and Ultrabasic Rocks. · Orthomagmatic Copper-nickel-iron (-platinoid) Deposits Associated with Basic and Ultrabasic Rocks. · Greisen Deposits. · The Skarn Environment. · Disseminated and Stockwork Deposits Associated with Plutonic Intrusives. · Stratiform Sulphide, Oxide, and Sulphate Deposits of Sedimentary and Volcanic Environments. · The Vein Association and Some other Hydrothermal Deposits. · Strata-bound Deposits. · Sedimentary deposits. · Residual Deposits and Supergene Enrichment. · Industrial Minerals. · Short notes on Selected Industrial Minerals. · The Metamorphism of Ore Deposits. Part 3: Mineralization in space and time - The global distribution of ore deposits: metallogenic provinces and epochs, plate tectonic controls. · Ore mineralization through geological time.
