Quantitative analysis of actinolite in the Pilsen Basin area by X-ray powder diffraction
Chlupáčová, Monika ; Havlíček, David (advisor) ; Nižňanský, Daniel (referee)
Increased concentration of suspended particles of the PM10 fraction, transportation and construction industry have serious impact on health. In Pilsen, the Air Improvement Programme in Pilsen Municipality takes place in accordance with the Pilsen Municipal Development Programme, the Regional Emissions Reduction Programme of the Pilsen Region and the National Emissions Reduction Programme of the Czech Republic. This thesis aims on determining the content of actinolite, azbestos mineral from amphibole group, in the samples from the Pilsen Basin. Altogether 23 samples from Pilsen municipal area were measured using the quantitative analysis method and X-ray powder diffraction. The actinolite content was determined in the samples.

Crystal chemistry of micas from České středohoří
Goll, Jan ; Skála, Roman (advisor) ; Ulrych, Jaromír (referee)
Six methods have been used to study micas from České středohoří mts.: X-ray difractometry (transmission and reflection), ICP MS, electron microprobe, Mössbauer spectroscopy and termogravimetry. The measurements of trace elements and REE's revealed very low tendency by normalization on chondrite reservoir and primitive mantle. Micas show high contents of TiO2 (9,47 wt.%) and BaO (up to 2,1 wt.%) in separated grains from rock. The micas classifications were determined by Tischendorf (2007) and Rieder (1998) as Fe-phlogopites. X-ray powder diffraction revealed cell dimensions and a common polytype 1M with space group C2/m. By Mössbauer spectroscopy have been studied the rates of Fe2+ /Fe3+ and they were 1,08 - 1,86 (except rock sample, which were 9:1). Termogravimetrical measurement until 1450řC revealed weight jump from 1120řC to 1270řC.

Chemical and Spectroscopic Characterization of Celtic Metal Artifacts
Išková, Petra ; Skála, Roman (advisor) ; Šrein, Vladimír (referee)
The thesis comprehensively investigates 2 pcs of ferrous and 14 pcs of bronze Celtic artefacts from a region of Zdejciny by Beroun. The study by means of ore microscopy, x-ray fluorescent microspectrometry, chemical microanalysis, Raman microspectrometry and x-ray powder diffractive analysis has showed that the bronze artefacts are made mainly of bronze. The phases present in the studied items correspond to fields and + of the Cu-Sn phase diagram. Content of Sn in bronze ranges between 4 and 33 wt.%. For the bronze selected items there was also Vickers microhardness measured. There were two artefacts where areas with a significant lead enrichment were found. Corrosive products were also deeply analysed and identified.

Crystal chemistry of micas from České středohoří

Micas from České středohoří mts. have been studied by X-ray difractometry, ICP-MS and electron microprobe. The measurements of trace elements and REEs revealed very low tendency by normalization of chondrite reservoir and primitive mantle. The micas classifications were determined by Tischendorf (2007) and Rieder (1998) as Fe- or Fe-Ti phlogopites. The abundances of Ti are very high up to 0,46 (a.p.f.u.). X-ray powder diffraction revealed double layered polytype 2M1 with space group C/2c.
