Current Projects

APVV-18-0065 – investigator (2018-2023, principal investigator P. Bačík) „Light litophile elements (Li, Be, B) in selected minerals: from crystal structure to geological processes”

The project includes mineralogical and crystal-chemical studies of minerals that contain light cations from the second period of the periodic system – lithium, beryllium and boron in their structure. Research is focused on two areas and two types of minerals will be examined. The first area of research will focus on crystal-chemical patterns down to the subatomic level using state-of-the-art analytical methods. The second area will be focused on the behaviour of these elements in the mineral and rock environment. Firstly, minerals containing Be, B and Li directly in their crystal-chemical formula (these elements are dominant at least at one structural site) will be studied. These include silicates (tourmaline supergroup, gadolinite supergroup, beryl and cordierite, Li mica, spodumen, bertrandite, phenakite), borates (whole class), phosphates (herderite) and oxides (chrysoberyl). However, we will focus also on the minerals in which Be, B and Li substitute for the other cations, but are not dominant. In this context, the distribution of studied elements in various minerals in variable rock environments will be studied..

VEGA 1/0137/20 – investigator (2020-2022, principal investigator P. Bačík) „Experimental study of physico-chemical properties of selected minerals (oxides, phosphates and silicates).”

The experimental mineralogical approach is suitable for detailed crystal-chemical study of properties and processes within the crystal structure and its stability, but also for the precious stones treatment within the gemmology. Some of these experiments are not sufficiently described and the colour changing mechanisms are similarly not clearly known as well as the processes leading to the mineral structure breakdown. The crystal-chemical properties of selected minerals (oxides, phosphates and silicates) will be studied by thermal, thermal-pressure and radiation experiments, especially the oxidation or reduction of cations, the formation or disappearance of colour centres and structural defects. The mineral decomposition processes and new phase formation will also be studied under experimental conditions.

VEGA-1/0151/19 investigator (2019-2021, principal investigator prof. M. Putiš) „Petrology and geochronology of crustal and mantle dyke systems in Cretaceous accretionary wedge of the Western Carpathians and eastern Austroalpine margin”

Cretaceous accretionary wedges of the Western Carpathians and the Austro-Alpine unit of the eastern Alps contains dykes of the crustal and mantle rocks. These rocks are significant indicator of Permian-Triassic or Jurassic-Cretaceous extension and the opening of the Neotethys and Atlantic Tethys respectively. They are of the key importance for the reconstruction of palaeotectonic and geodynamic evolution of the Carpathians and Alps. The mineral rock composition (EPMA, LA-ICP-MS) and their whole-rock chemistry (ICP-MS) will be used for definition of their palaeotectonic origin. The isotopic study (Rb/Sr, Lu/Hf, Sm/Nd. U/Pb) of the rocks and minerals, and their isotopic dating (U-Pb SIMS, nano-SIMS, LA-MC-ICP-MS, K-Ar) will enhance creation of geodynamic evolution model of mentioned accretionary complexes. Their occasional economic potential can be estimated. We will utilize possibilities of our broad international co-operation particularly in isotope geochronology.
