Syllabus
  • The education is focused above all on mastering the practical tasks of optical mineralogy. 1) Introduction to optical mineralogy:  refraction and polarisation of light, Becke line, positive and negative relief of minerals, refractive indices (index of refraction), total reflection, birefringence  optical properties of isotropic minerals  optical properties of anisotropic minerals - uniaxial - biaxial 2) Work with polarising microscope Microscopic study of minerals in polarised light:  determination of the nicol position, determination of extinction angle, interference colours and birefringence height  function of compensating plates and quartz wedge, their usage the character of the zone (ráz délky, charakter délky)  conoscopy and optical character of minerals: - uniaxial - biaxial 3) The course of determination of minerals in thin sections using polarising microscope: The system of rock-forming minerals: hours of practicals *quartz, potash feldspars, plagioclases (basicity of plagioclase determined with planar table of the polarising microscope 6 *nefeline, leucite, sodalite, nosean, hauyn, analcime 3 *olivine, pyroxenes, amphiboles 3 *muscovite, biotite, phlogopite, cinnvaldite 3 *carbonates, barite, tourmaline, garnets 3 **allanite, zoisite, epidote, klinozoisite, mellilite, chloritoid, 3 **chlorite, glaukonite, minerals of the serpentine group, talc 3 **andalusite, sillimanite, kyanite, cordierite, vesuviane, wollastonite, 3 **gypsum, anhydrite, fluorite, halite, zeolites 3 ***skapolite, chondrodite group, prehnite 3 ***kankrinite, mullite, periklas, spinels, staurolite, dumortierite, lawsonite, pumpellyite, brucite 3 ***corundum, rutile, apatite, zircon, titanite, beryl, topaz, monazite 3 Note: the division of minerals is not on classification pronciples, but according to the level of required knowledge: Minerals marked* need unconditionally be recognized, ** are possible to be discussed *** overlooking in the thin section does not influence the grading Scheduled for 12 weeks of the semester
