Preface. Introduction: The importance of sedimentary organic matter. The nature of organic matter in sediments. Production and delivery flux of planktonic organic matter. Biological degradation and consumption of organic matter. Abundance of organic matter in sediments: TOC, hydrodynamic equivalence, dilution and flux effects. Organic matter preservation: the effects of oxygen deficiency. Origin and nature of the phytoclast group. Origin and nature of the amorphous group. Origin and nature of the palynomorph group, phytoplankton subgroup. Origin and nature of the zoomorph subgroup, and the origin, nature and distribution of the zooclast group.
