Course objectives
Main objectives can be summarized as follows:
- to understand the basic problems in mineralogy and their parts ( Introduction to mineralogy and geochemistry, Morphological and structural crystallography, Chemical and physical mineralogy and Descriptive mineralogy).
- descriptive mineralogy is focused on crystallochemical classification of minerals, structure, chemical composition and properties of main minerals according to syllabus
- to understand main geochemical processes in Earth-s crust (magmatic, metamorphic and weathering)
- to recognize antropogenic influence on chemical development on the surface of Earth-s crust
Learning outcomes
Student will be able to:
- have basic knowledge of morphological, structural, chemical and physical crystallography
- know the main characteristics of about 50 most abundant and industrially important minerals
- explain the basic geochemical processes taking place on the planet Earth, especially in the Earth's crust and its surface
Syllabus
  • 1.Introduction to mineralogy and geochemistry. History of the mineralogy and geochemistry, literature. Mineralogy and geochemistry in Earth-s sciences.
  • 2.Crystal. Elements of crystal morphology (faces, crystal forms). Crystallographic coordinate systems. Indexing of crystal faces (according to Miller, Weiss). Measurement of the angles of crystals, goniometers. Crystallographic principles. Elements of morphological symmetry of crystals, symmetry operations, the 32 point groups. Crystal classes (crystal axis systems, crystal forms). Crystal form and habitus, crystalline aggregates. Twinning, pseudosymetrie, pseudomorphie.
  • 3.Crystal and properties of its growth. Nucleation. Defects of growth mechanism. Compositional zoning. Effects of temperature and pressure on crystal growth. Lattice symmetries, unit cells, symmetry operations of lattices. The 14 types of Bravais cells, the 230 space groups. X-ray crystallography (diffraction, X-ray powder diffraction, powder difractometers, identification of powder patterns, refinement of lattice parameters).
  • 4.Chemical mineralogy - The model of the atom, ions, chemical bondings, the ionic structures and properties of ionic crystals. The covalent model, the metallic bond model and its properties, the molecular structures. Crystal chemistry of minerals. Calculation of chemical formulas from the mineral analysis.
  • 5.Physical mineralogy (color and streak, luster and transparency, cleavage, fracture, tenacity, density, hardness, magnetism, fluorescence and radioactivity). Properties depending upon light. The behavior of light in minerals. Refractive index. Relationships between optical properties and symmetry. Isotropic minerals. Optical properties of uniaxial minerals. Optical properties of biaxial minerals.
  • 6.Introduction to descriptive mineralogy (crystallochemical classification of minerals, mineralogical nomenclature, mineral, variety). The native elements (Au, Ag, Cu, Pt, Fe, As, Sb, diamond, graphite, S) Sulfides: tetrahedral (sphalerite, chalcopyrite), octahedral (galena, pyrrhotite, niccolite), with unusual coordination (molybdenite, cinnabar, argentite), complex sulphides (pyrite, marcasite, arsenopyrite, stibnite, tetraedrite, proustite, pyrargyrite, realgar, orpigment). The halide minerals (halite, sylvite, carnallite, fluorite, cryolite) Oxides and hydroxides: tetrahedral ( the SiO2 minerals, periclase), oktahedral (hematite, corundum, ilmenite, rutile, cassiterite, mixed tetrahedral and octahedral (magnetite, spinel, chromite), cubic (uraninite). Goethite, lepidocrokite, diaspore, boehmite, limonite, bauxite. The sulfate minerals: anhydrous (anhydrite, barite), hydrous (gypsum, chalcanthite, melanterite, epsomite, alunite). Carbonates: calcite structure type (calcite, magnesite, siderite), dolomite structure type (dolomite, ankerite), aragonite structure type (aragonite, cerussite), other structures (malachite, azurite). Nitrates (nitratite, niter). Chromates and molybdates: scheelite, wolframite Phosphates, arsenates, vanadates: xenotime, monazite, apatite, pyromorphite. The silicate minerals: network silicates (feldspars, feldspatoides, beryl), layer silicates (talc, muscovite, kaolinite), chain silicates (pyroxenes and amphiboles), ring silicates (turmalines), single tetrahedral structures (olivine group, garnet group, titanite, topaz, zircon).
  • 7.Introduction to geochemistry. Geochemical processes in Earth-s crust (magmatic, metamorphic and weathering). Antropogenic influence on chemical development of Earth-s crust.
