✦ Synopsis

occurrence of weak autoxidation processes has been observed in the coal seam at a depth from 3 to 5 m. Mierinite whose percentage is relatively high has been formed as a result of high temperature processes that take place in the peat. The higher amount of imerinite macerals predetermines the higher oxidative stability of this coal.

02/01272 Peculiarities of gas content and metamorphic changes in coals in the southwest coal region of the Lvov-Volyn Basin

Kruglova, R.L. Geol. Geokhim. Goryuch. Kopalin, 1999, 4, 70-75. (In Ukrainian) Methane content and metamorphism of coal, both regionally and in the stratigraphic section of coal seam, were studied. A close connection of the methane content with the coalification degree and coal depth was established.
