Graduated from the Geological Faculty of Moscow State University in 2018, in 2021 graduated from the PhD programme of the Geological Faculty of Moscow State University on the study of the genesis and distribution of refractory clays. Member of expidition in geological survey work on the Niryungda basin (Krasnoyarsk Territory) as part of the crew of the GEOKHI RAS in 2016, as well as in exploration work of the Norilsk group deposits in 2018. In 2019, took part in the Moroccan expedition to map contour deposits and 53- m voyage of the R / V Akademik Nikolay Strakhov as part of the IO RAS team. Currently, a researcher at the Department of Geology, Geochemistry and Economics of Mineral Resources, Moscow State University.
Application of portable LIBS and XRF SсiAps analysers for field geochemistry.
The presentation will demonstrate methods of determining the grade of refractory clays of the Shulepovskoye field using a portable LIBS analyser. Previously, all the material was analyzed using a benchtop XRF spectrometer, and later, using the SciAps Z-300, spectral data was collected, according to which the calibration scales were built to form a LIBS calibration for refractory raw materials. On the other hand, the spectral data obtained was mathematically classified (without taking into account the chemical composition of the samples) to distinguish groups according to the grade of raw materials, which makes it possible to quickly determine the type of refractory clay immediately.
