Abstract:
A Nyugati-Mecsekben elhelyezkedő Bodai Agyagkő Formáció (BAF) a nagy aktivitású radioaktív hulladékok elhelyezésére szolgáló mélygeológiai tároló potenciális befogadó képződménye. Mivel a BAF porozitása és permeabilitása extrém kicsi, így abban fluidumáramlási útvonalak törések, szerkezeti inhomogenitások mentén jöhetnek létre. Ebből adódóan kiemelkedően fontos a BAF deformációtörténetének megismerése, melyről a repedések, repedésrendszerek hordoznak információt. Kutatásunk során a Boda község közelében mélyült BAF–2 fúrás 74,34–899,22 m közötti mélységtartományából származó 56 db fúrómagminta

Abstract:
Heavy metals such as lead, chromium, cadmium, copper, mercury, and arsenic which are industrial by-products can have negative impact on the environment if they not managed properly. Biosorption is environmentally-friendly waste treatment method. The advantage of biosorption compared to other waste treatment method is ecotechnology, which means effective, cheaper than chemical treatment and environmentally-friendly technology. Using the concept of bioremediation-based on microbial enhanced recovery of metals (MERM) allows the possibility of concentration process (bio-concentration) of metal con

Abstract:
This thesis examines the principle of the Raman phenomenon and the function of the Raman spectrometer in order to build a low-cost Raman spectrometer assembly for school laboratory teaching. The thesis lists the important parts of the device and describes their key features. Subsequently, the selection of each component is discussed and a basic experiment is performed to verify the principle of this spectrometer. In the final part, a low-cost Raman spectrometer is constructed and tested thanks to the knowledge gained.

Abstract:
The detection of mineral phases under in situ conditions has become a primary but sometimes also challenging task in many fields of geoscience. Raman spectroscopy has been used as a powerful tool for the identification of various minerals and organic compounds. The advantages and the relative simplicity made this method a promising choice in the future planetary exploration missions to Mars. The deposits of aqueous minerals including sulfates have been found on the Martian surface. With the development of miniaturized handheld spectrometers there is a need for evaluation of Raman spectroscopy

Metamorphic processes can transform the organic matter in sedimentary rocks into structurally organized carbonaceous matter, in ideal conditions to graphite. In the centre of West Alpine arch, the metasedimentary rocks are rich in dispersed carbonaceous matter and were used in this thesis to specify the thermal range of metamorphism based on the structural state. Previous studies have used mainly the Raman spectrometers to determine the structural state of carbonaceous matter. Unfortunately this method doesn't allow in-situ analyses which, in addition to Earth studies, can be essential for stu

This Ph.D. thesis was focused on the application of Raman spectroscopy as the main analytical method for the characterization of neo-formed minerals, notably sulfates, from burning coal waste dumps. This environment associated with subsurface fires gives rise to a variety of uncommon and rare minerals. The specific features of these minerals (metastability, hygroscopy, mixed aggregates) causes that the mineralogical investigation is a challenging task using traditional laboratory-based techniques.
