Subject aims expressed by acquired skills and competences
The student knows and can use microscopic techniques to identify rocks and minerals. It can explain the basic principles of the microscopy of minerals and rocks in passing and reflected light. Next, it can prepare a rock sample into a microscopic thin section. He can apply his knowledge to microscopic observations of basic minerals and rocks.

Summary
In the subject, the student learns basic microscopic techniques in determining minerals and rocks by passing and reflected light, and the basic optical characteristics of selected rock-forming and ore minerals, expanded by an overview of the structures of igneous, sedimentary and metamorphosed rocks.
The subject is divided into two parts: microscopy in reflected and passing light. They will present the building of a microscope, species of slides for microscopy, various microscopic techniques and digital image analysis tools, determination of the optical properties of rock-forming and ore minerals, etc. In the practical part of the subject, the tudent will prepare microscopic slides itself in the form of a cross section and polished coating.

1. Character of light - theoretical introduction. A quarry and a reflection of light. Polarization of light. The breakdown of substances according to optical properties. Polarization microscope.
2. Determination of grain size. Properties of minerals observed in uncut nickels. Preparing microscopic slides - selecting rock and cutting it.
3. Characteristics of minerals when observed in cross-linked nickels. Discarding. Interference colors. Lapping and grinding the slide.
4. Compensators. Clots and transformations. Character of the zone (stroke of length). The optical nature of the mineral. Working with compensators. Sticking the slide.
5. Systematic mineralogy – an overview of the optical properties of selected rock-forming minerals. Polishing the process and finalising it.
6. An overview of magma rock structures.
7. Overview of sedimentary rock structures.
8. Digital image analysis and its possibilities in mineralogy and petrography. Special microscopic techniques, dark fields, fluorescence.
9. Reflected light, inverse ore microscope design, types of screens, eyepieces and lenses.
10. The types of microscopic preparations used in reflected light, the preparation of the coatings.
11. The color of minerals, the difference between minerals colored and colorless. Errors in determining mineral color.
12. The luminosity of ore minerals and coal mass. Observations in exterior slanting light - the internal reflexes of ore minerals.
13. Characteristics of minerals in polarized light, sources of error in observations in polarized light. Evaluation of a set of unknown ore minerals in reflected light in terms of their optical properties.
