Abstract. Results of research on evaluating gas inclusion volumes in quartz grains of Donbas sandstones are presented. Sandstone thin rock sections from samples, which were taken within the middle and late catagenesis substages, were studied. The thin rock sections were examined by optical microscope ПОЛАМ – Р111 with magnification of 100 - 1200 times and with immersion solution. It is stated that during the transition from middle to late catagenesis substages, total amount of gas inclusions in quartz sandstone grains decreases. This process is different in isolated inclusions and inclusions that decorate the Böhm strips. The results can be used in studying the gas-form transformations in the rocks and gas-dynamic phenomena in the rock mass.

Keywords: gas inclusions, quartz grains, sandstone, paleodepth, carbonic deposits.
