Analytical Facilities
Stable Isotope Mass Spectrometry
Research areas
Mantle petrology and geochemistry: petrology and geochemistry of mantle-derived igneous rocks and their xenoliths. Genetic studies on rare earth element minerals, with special attention to monazite formation processes and U-Th-Pb age determination by electron microprobe analyses. Isotope geology : isotope geochemistry of upper mantle materials (alkaline basaltic rocks, carbonatites); isotope geochemistry of mass extinction events and stable isotope stratigraphy. Isotope hydrology: water base protection; secular variation of river waters and related sediments; origin and mobilization of cave and thermal waters. Stable isotope investigations on carbon-dioxide in air in order to determine regional CO2 emmission and absorption processes. Stable isotope geochemistry of soils with special attention on carbonate formation, redistribution and alteration processes. Archaeological applications by means of geochemical methods with special attention to the origin and production technology of Avar Period glass beads.

Theoretical, methodological problems, systematics and nomenclature of low-temperature metamorphism. Diagenetic and metamorphic transformations of phyllosilicates. Temperature - pressure - time relations of Alpine metamorphism in the Carpathian Basin and in the surrounding regions. Application of geothermometric and geobarometric methods for distinguishing polymetamorphic events in the Carpathian Basin. Modelling of metamorphic processes using quantitative phase diagrams Metamorphic petrogenetic interpretation of the Mesozoic ophiolites in NE-Hungary. Mn-ores and related sedimentary rocks: genetic studies by means of petrologic and geochemical investigations. Distribution of certain bio-essential elements in the rock - soil - water system in model areas representing rural and antropogenic effects in various proportions (Cserhát Hills, Börzsöny Mts., etc). Experimental modelling of cation adsorption on swelling clay minerals aiming at the determination of environmental geochemical characteristics of soils. Origin of thermal waters, their organic matter content, and its transformations studied by complex organic geochemical methods. Applications of geochemical, mineralogical and petrographic methods in archeometry: weathering under natural and antropogenic conditions. Studies on formation of hydrocarbons (oil and gas), with special regard to the determination of formation temperatures, pyrolisis of asphaltenes, distribution of isoprenoids and trace element content of oils.
