Monitoring of chemical composition changes in wine during the wine making process
Orságová, Marie ; Punčochářová, Lenka (referee) ; Diviš, Pavel (advisor)
The Chardonnay wine variety was harvested in the region of Znojmo on the wine rout Načeratický kopec. In connection with the entire winemaking process of this particular variety, research was focused on mineral concentration changes during the maturation process. The theoretical part characterizes the technology of wine production, as well as the classification and chemical composition of wine. In the experimental part, the analytical technique of inductively coupled plasma optical emission spectrometry (ICP-OES) was used for the determination of minerals (K, Ca, P, Mg, Na, Zn, Cu, Fe and Mn) in wine. The data show the differences in the concentrations of all macroelements and microelements during the whole wine production technology.

Mineral and chemical changes of magma crystallization during formation of post-Variscan intrusions and veins in the Moldanubian Zone of the Bohemian Massif

- 1 - English abstract The late-Variscan magnesium-rich potassic to ultrapotassic igneous rocks create numerous dykes, dyke swarms and several plutonic bodies at the boundary between the Moldanubian Zone and the Teplá-Barrandian Block of the Bohemian Massif. They represent a volumetrically smaller group of igneous rock but they are the key to understand generation of melt and processes of mantle metasomatism and shallow-level magma differentiation. In addition, they are considered as an indicator of the tectonic evolution of this part of the Bohemian Massif during the final stages of the Variscan orogenesis. Currently, they are the subject of discussion by several authors in terms of their genesis, emplacement time and geodynamic significance. The presented thesis is a compilation of four scientific publications that are aimed at the petrological study of selected (ultra)-potassic dyke rocks from several localities at the western border of the Moldanubian Zone. The study of mineral textures, mineral chemistry and whole-rock geochemistry together with magnetic fabrics, structural field relations and age determinations allowed us to describe the crystallization history of these rocks, discuss their evolution from melt generation to magma ascent and emplacement, and form the model of sequence of Variscan...
