Abstract (in english)
   The changes in the composition of fossil organic matter from the tertiary brown Coal Basin, Carboniferous Coal Basin and Silurian black shales during natural weathering have been studied using the ROCK EVAL pyrolysis method. The most sensitive pyrolysis parameter has been found to be the hydrogen index IH, the amount of H-bound carbon compounds related to the concentration of organic carbon, C org.IH of Tertiary algal shales decreases by 10after one year of weathering on a spoil bank to the observed minimum of about 30of the original value after 35 years of weathering in antural profile is comparable with that of 20 years on spoil bank. Weahering of Carboniferous coal and Silurian shales can reduce the IH values by more than 95
