The experimental results on the synthetic oil production from Domanik Formation rocks under hydrothermal conditions are given. Oil fractions extracting potential of the rocks under hydrothermal was shown to be up to 60 mg/g or 6,0 wt.%. Inorganic additives (sodium carbonate or silica) incorporation does not influence on the oil recovery factor. Meanwhile the amount of recoverable oil products depends on the mineral composition of the rock. The dependence between the percentage of hydrocarbons emission and mineral composition of the rocks was determined. Clay minerals and silica increase the yield of synthetic oil, carbonates, conversely, inhibit the process.

The technique of decomposition of samples with a hardly soluble complex matrix (sintering with soda) for subsequent determination of trace element composition by high-resolution mass spectrometry with inductively coupled plasma is improved and tested. Analytical and methodological problems arising in the process of preparation of the samples under analysis for analysis are described, directions for their solution are indicated. The correctness of the developed sample preparation procedure has been verified by means of a comparative analysis of various methods applied to international certified standard rock samples.
