It is devoted to basic methods of optical identification of minerals in transmitted and reflected light in relation to the use of computers equipped with image analysis. The basic range of rock-forming and ore minerals is enhanced with an overview of the structures of igneous, sedimentary and metamorphic rocks.
Schedule exercise of microscopy in transmitted light is as follows:
1st exercise
The character of light - theoretical introduction. Refraction and reflection of light. Polarization of light.
The distribution of substances by optical properties. Polarizing microscope.
Preparation of microscopic slides. Determination of grain size. Properties of minerals during observation nezkřížených not.
2nd exercise
Properties of minerals when viewed in crossed not. Quenching.
Interference colors. Compensators. Adhesions, and transformation.
Character Zones (character length). Optical character mineral. Working with compensators.
3rd exercise
Systematic Mineralogy - an overview of the optical properties of selected
rock-forming minerals.
4th exercise
Overview of the structures of igneous rocks.
5th exercise
Digital image analysis and its possibilities in mineralogy. Submission and checking of entered programs.
Schedule exercise of microscopy in reflected light is as follows:
Reflected light:
1st Exercise:
The construction of the microscope, the types of curtains, eyepieces and objectives, vertical illuminator (indoor vertical, internal oblique lighting, external oblique lighting).
2nd Exercise:
Types of drugs used in reflected light microscopy (theory and demonstration of making polished sections in the laboratory). Centering microscopes, centering the lamp.
3rd Exercise:
The color of minerals, the difference between colored and colorless minerals. Errors in determining the color of minerals. The reflectivity of ore minerals and coal.
4th Exercise:
Observations of the external oblique lighting - interior reflections of ore minerals. Properties of minerals in polarized light, sources of errors in observation in polarized light.
5th Exercise:
Evaluation of sets of unknown ore minerals in reflected light in terms of their optical properties.
Passing the final test of the reflected light.
