Laboratory of Geochemistry and Mineralogy

Contact: Nata-Ly Pantšenko, +372 620 3049


  •     Determination of elemental composition by XRF method
  •     Determination of mineral composition by XRD method

The laboratory of geochemistry and mineralogy mainly deals with studies of the elemental composition and structure of rocks and other materials.

A Bruker D8 Advance X-ray diffractometer (XRD) with a powder diffractometry setting is used in the laboratory for mineralogical and structural studies. In geology, the method is a basic tool for determining mineralogical composition and allows to study structural changes in minerals as a result of various environmental influences.

The laboratory uses a Bruker S4 Pioneer fluorescence spectrometer (XRF) to analyse the elemental composition, with which it is possible to determine the content of a wide range of chemical elements from fluorine to uranium in the content range of 10ppm – 100%.

In addition to Bruker S4 Pioneer spectrometer, Vanta M-series handheld XRF spectrometer is utilised. It allows for a fast initial overview of elemental composition of a material.

As for the preparation of samples, the laboratory is equipped for sawing, crushing and grinding rocks and making thin and polished sections.

The laboratory has long been participating in the International Association of Geoanalysts benchmarking programme, which aims to provide feedback on the quality of laboratory analysis (see certificates). The laboratory is comprehensive, and in addition to research, it also participates in national projects and cooperates with private companies, such as chemical engineering companies, metallurgical industry, pharmaceutical industry, road construction companies, etc.

Certificates: dolerite, phosphorite, siliceous siltstone, granodiorite, sediment, tonalite, sandy loam, sandy loam2, monzonite, basalt, calcified sediment, leucomonzogranite, granite, metalliferous shale, tholeiitic basalt, basalt

Laboratory of Isotope and Hydrogeochemistry

Contact person: PhD Merlin Liiv, +372 620 3030


  • Isotopic composition of organic matter and water

Isotopic composition of organic matter (carbon and nitrogen) in sediments and other samples are analysed using FlashEA 1112 coupled via ConFlo IV to a Delta V Advantage Isotope Ratio Mass Spectrometer. Sample precision and calibration of data is performed using International Atomic Energy Agency (IAEA) standards.

The isotopic composition of water samples (δ18O and δD) is determined with a Picarro L-2120-i laser spectrometer.

The Laboratory of Sedimentology and Palaeoecology focuses on studying natural and anthropogenic changes in the environment, climate and vegetation based on information preserved in sediments (lake, bog, marine, etc.). Various palaeoecological issues are addressed, such as the development of vegetation in changing climates, the impact of land use on landscape formation (analysis of pollen and plant macrofossils), natural processes and human influence on water bodies (analysis of diatoms etc.)
