Abstract
Fragment composition of humic acids isolated from solid caustobioliths of varied genesis and from soil was subjected to a comparative analysis. It was found that the composition of these humic acids is affected by the mechanochemical treatment conditions. It was shown that a mechanochemical treatment leads to a decrease in the molecular mass of humic acids to a varied extent for all caustobioliths and to an increase in the content of aromatic fragments in their structure and in the degree of their oxidation.
