Relationship of Organic Matter and Mineral Diagenesis
This course attempts to focus on selected aspects of the organic/inorganic interaction within carbonrich marine sediments and sedimentary rocks in potentially petroliferous basins. The course begins with a discussion of the effects of early diagenesis upon the accumulation of organic matter and ways in which the early diagenetic environment can be interpreted from evidence in ancient sediments. The course then focuses upon rock-water interaction and upon generation, distribution and significance of aqueous organic species in petroliferous basins. The final section concerns mechanisms of organic/inorganic interactions in sandstone/shale sequences, with particular emphasis upon the development of secondary porosity. The author concentrates on processes at temperatures between 80 and 200 degrees Celsius and upon the links between fine-grained hydrocarbon source beds and reservoir rocks and the transfer and redistribution of material in the subsurface.
