Course objectives
Main objectives are basic knowledges in the laboratory research of rocks and minerals; especially in:
- basic operations (sampling and sample treatment, mineral separation)
- chemical methods (wet silicate analysis)
- instrumental methods (electron microscopy, electron microprob)
- spectral analyses in gamma, X-ray, UV, VIS, IR range
- electrochemical and chromatographic methods
The course is aimed to students of the Bachelor programs and it involves lab practices.
  • Sampling and sample treatment: Sampling of rocks and minerále in the field, technical tools. Optimum sample size, representativeness. Criteria for the choice of suuitable analytical methods (purpose, price, sensitivity, required sample size). Sample preparation for analysis - crushing, sieving, homogenisation. Mineral separation techniques: gravitational (panning, heavy liquid separation), magnetic (with permanent magnet, electromagnetic). Elutriation (Stokes' law, Kopecký's elutriator), flotation. Hand picking. Preparation of thin and polished sections.
  • Macroscopic determination of mineral and rock properties: subjective colour scale, hardness, scratch, smell, cleavage, fluorescence, radioactivity. Density measurement. Refractive index measurement. Mineral luminescence, radioactivity, radiographic methods.
  • X-ray methods: Theoretical basics (Bragg's equation). Powder method, diifractometer arrangement. Specimen preparation. Evaluation of X-ray patterns - qualitative analysis, phase identification. Quantitative phase analysis (RIR, internal standard method). Determination of lattice parameters, Rietveld's refinement method. Monocrystal methods. The possibilities of X-ray data usage.
  • Thermal methods: Differential thermal analysis - method principles, thermal reactions of minerals, instrumentation. Interpretation of DTA and TG patterns, qualitative and quantitative analysis. Differential calorimetry, dilatometry, thermoluminiscence, decrepitometry. Examples of application of thermal methods in geology.
  • Electron microscopy Basics of scanning and transmission electron microscope, imaging modes. Electron diffraction. Image analysis.
  • Electron microanalysis Wavelength-dispersive method, energy-dispersive method. Less common microanalytical methods (ion microprobe, laser ablation probe). X-ray fluorescence spectroscopy.
  • Chemical analysis: Analytical error, accuracy and rightness of the results, relative and absolute error, relative and absolute error, systematic, random and gross error, normal distribution of random errors, standard deviation, error propagation, confidence interval. Classification of analytical methods, their applicability. Choice of appropriate method, direct and indirect methods, analytical costs.
  • Classical methods: Gravimetric methods, precipitation, filtration, decanting, examples of usage (determination of SiO2, S), typical analytical error. Volumetric methods, titration, titration agent, indicators, examples of usage (complexometric determination of Ca, Mg, Al, oxidimetric determination of Fe, acidimetric determination of SiO2), typical analytical error. Separation methods, extraction, ion exchangers.
  • Instrumental methods. Classification (optical - spectral, non-spectral, electrochemical, chromatographic), usage, typical errors, evaluation in relative methods (calibration curve, standard addition, inner standard method).
  • Emission spectral methods Spectrum formation (radio-wave, micro-wave, far-, near- and medium infrared, ultraviolet, X-ray, gamma-ray range), possible uses, methods (emission spectrography, flame photometry, emission spectrometry with inductively coupled plasma, neutron activation analysis).
  • Absorption spectral methods: Formation of absorption spectra, Lambert-Beer law, methods (vibration spectroscopy, atomic absorption spectroscopy, infrared spectrometry), possible uses, typical instrumental arrangement.
  • Elektrochemical and chromatographic methods: Electrochemical potentials, pH measurement, ion-selective electrodes; polarography. Chromatography, instrumental arranfgement, mobile and stationary phase, gas- and liquid chromatography, appplication, advantages, errors.
