Brief description of the lecture:
Course topics:
During the course the students deal with the instrumental analytical methods used in mineralogy, petrology and geochemistry. The theoretical principles of several measurement methods. Possible implementations, measurement range, accuracy, selectivity, reproducibility, precision. Reliability of results. The interpretation of results and their use in geosciences. The geological applicability of the presented methods.
Methods:
- Electron microprobe
- Fluid inclusion microscopy
- Gas chromatography-Mass spectrometry
- High-pressure liquid chromatography (HPLC)
- Infrared spectroscopy
- Raman spectroscopy.
- Rock-Eval pyrolysis
- Scanning electron microscopy
- Transmission electron microscopy
- X-ray diffraction
- X-ray fluorescence spectrometry
Lecture:
The theoretical principles of several measurement methods. Possible implementations, measurement range, accuracy, selectivity, reproducibility, precision. Reliability of results. The interpretation of results and their use in geosciences. The geological applicability of the presented methods.
Laboratory practice:
The students analyse their tasks under the supervision of the teacher. They define the data types needed to solve the task and choose the appropriate method that will provide the necessary information. The students have to decide which are the methods that complete each other and that the students certainly have to use. They verificate the results with the use of further methods, if it is possible. They make work plans and assign the roles in the measurement processes.
While using the methods categorised into Group A the students contribute to the preparation of the sample and the execution of the measurement. If it is necessary they also contribute to the calibration of the instrument. While using the methods categorised into Group B the students receive the raw data from the measurements.
The students who executed the measurement have to evaluate the results. The members of the various working group who contributed to the measurements related to the given task have to prepare the geological interpretation. They will also present their work, the results and the conclusions in a brief presentation. After the presentation the other students can ask their questions and make comments - similarly to a conference presentation and the following discussion. Finally, the students assesses how successful was the execution of the task.
