Geochemical Modes of Organic System and Paragenesis of Microelements in Coal

摘要

The paragenesis of microelements in coal signifies their concentration together within the organic system, which is associated with the formation of organic compounds and authigenic minerals. Interest focuses on the geochemical environments: in particular, the oxygen, carbonate, hydrogen-sulfide, and chloride environment, as characterized by the activities of the corresponding components. The concentration of microelements in such environments is analyzed. In each set of conditions, the paragenesis of microelements strongly bound to the organic and mineral masses will be different.
