PhD. Topic

Crustal xenoliths in alkali basalts in Southern Slovakia

Plio-Pleistocene alkali basalt volcanism in southern Slovakia is characterised by the presence of various volcanic phreatomagmatic structures. One important feature of these basalts is the presence of crustal xenoliths. Various magmatic xenolith types have already been described and very well characterized. The literature on metamorphic xenoliths of this region, (e.g. skarn and granulite xenoliths) is not as complete as the one relative to magmatic xenoliths. These xenoliths were not studied in equal extent, and therefore leave us with a series of unanswered questions, the main two, are: what is the history of these xenoliths? And what can they tell us about the deeper parts of the Southern Slovakia crust, and its evolution? This PhD project will be focused on determining the mineralogy, petrology and geothermobarometry of the metamorphic xenoliths present in the Plio-Pleistocenic Slovakian alkali basalts. Experimental procedures will focus on the use of the Electron Microprobe (EMP), to determine the major elements compositions of the various minerals of interest, mainly for geothermobarometry.

This project has the main purposes to sample and study new exotic xenoliths that were found and only preliminary investigated near Camovce village, Lucenec District, Southern Slovakia. They will be investigated under several different points of view. First of all, their internal structure will be defined via X-ray Computed Tomography (CT). Their mineralogy and petrography will be firstly qualitatively described through transmitted and reflected light microscopy, and in a second stage their characterization will be achieved quantitatively through Raman Spectroscpy, EMPA, SEM-BSE and X-rays mapping. The EMPA data will be used for the application of suitable geothermobarometers, in order to determine the pressure and temperature of formation of the different mineral assemblages. The whole rock composition and the rare earth and refractory items will be achieved by ICP-ES and ICP-MS analyses. These analyses will be used to produce a thermodynamic model of the chemical system in which the rock formed, in order to decipher the PT history of the xenoliths. This project will also co-finance my PhD, and the results of this project are planned to be published in internationally recognised journals.
