Abstract
A detailed study of the optically determined amorphous organic matter (type 1) in the water column and the sediments from eutrophic Lake Greifen provide a model for determining the pathway by which lacustrine algae are incorporated into sediments and later transformed into type 1 kerogens. Mass balancing of organic fractions (fulvic acids, humic acids, and stable residues (proto-kerogen)) in combination with infrared spectroscopy and gas chromatographic studies of these fractions suggest that two processes in the formation of kerogens are proceeding simultaneously: (1) selective decomposition of the structurally and functionally unique fulvic acids and (2) polycondensation/polymerization of structurally and functionally related fractions in the lacustrine algae leading to the formation of complex humic acids and finally to the stable residue phase.
