چکیده انگلیسی
Origin, composition and fate of organic particles in marine sediments are to a large extent unknown. Here we contribute to resolving this lack of information by reporting on the structural characterization (FTIR micro-spectroscopy, py/GC/MS and TMAH assisted thermochemolysis GC/MS) of hand-picked Thalassiphora pelagica dinoflagellate cysts (Oligocene). The cyst wall macromolecule is relatively condensed. It is composed of a mixture of aliphatic moieties with the linear carbon units having an average chain length of â¼12 carbon atoms. In the pyrolysate this is reflected in aliphatic series of alkanes and alkenes (both
