The Early Diagenesis of Organic Matter: Reaction at the Air-Sea Interfacemosphere and residual materials which eventually settle to the seafloor. There may be more evidence for interfacial processes leading to atmospheric products than for processes leading to sedimentary products, but the discussion in this chapter will be confined to the latter.

Determination of Structural Components of Kerogens by the Use of Analytical Pyrolysis Methodsd chemical degradation (including pyrolysis) and spectroscopic techniques have therefore been applied to the structural characterization of kerogen (see Durand, 1980). Some of the techniques most commonly applied today are those involving analytical pyrolysis methods, and it is those we discuss here.

The physiologies of living organisms combine with chemical, physical, and geological forces to continually redistribute these elements b

These inferences are drawn from established relationships between biological source materials and diagenetically altered compounds (de Leeuw and Largeau, this volume, Chapter 2).

The Early Diagenesis of Organic Matter in Lacustrine Sediments accumulation and composition of their sediments. The diversity of lacustrine depositional systems is useful to organic geochemical studies. Different aspects of the early, as well as the more advanced, stages of diagenesis can be investigated, using lakes that have sedimentary characteristics which
