Distribution of the Palynomorph Group: Phytoplankton Subgroup, Marine Dinoflagellate Cysts (Dinocys1, p. 401; Dale, 1976; Rogers and Bremner, 1991, p. 64). Within the same general region where the motile phase forms blooms, hydrographic and sedimentary processes commonly lead to the corresponding cysts being selectively deposited in areas of fine-grained sediment termed ‘seed beds’ (≤ 2000 km.; White and Lewis, 1982, p. 1186).

Introduction: The Importance of Sedimentary Organic Matter,on of the subject requires an understanding of the environmental controls which govern the production of organic matter in the biosphere, the ecological and sedimentological processes which control its deposition and distribution, the biogeochemical, and geomicrobiological factors which influence it

Halfhearted

The Nature of Organic Matter in Sediments, to burial, most geologists focus their attention on the much smaller fraction that survives diagenesis to become a potential source of hydrocarbons. However, the significance of the general terms ‘refractory’ and ‘labile’ (what is, or is not, degradable) depends very much upon one’s viewpoint and w

Biological Degradation and Consumption of Organic Matter, (electron donors) and oxidants (electron acceptors). Oxidation involves the loss of electrons (from the electron donor) and reduction involves electron gain (by the electron acceptor); oxidation and reduction reactions must occur in balanced pairs (redox couples). The energy required to remove elec

Abundance of Organic Matter in Sediments: TOC, Hydrodynamic Equivalence, Dilution and Flux Effects, (Jarvie, 1991). However, kerogen includes significant amounts of other elements, especially hydrogen (3–10 wt%), oxygen (3–20 wt%), nitrogen (0–4 wt%), and sulphur (0–4 wt%). The proportion of these elements is not constant but depends on the source, preservation state, age, and maturation of the o
