Roles of Organic Matter in Sediment Diagenesis
This volume is the direct result of an SEPM Research Conference held in October 1983 at Lost Valley Ranch, Colorado. The goal of the volume is to bring attention of the sedimentological community the importance of interaction of organic compounds with the inorganic sedimentary system and the degree to which organic compounds drive diagenetic systems. This volume comprises 16 reports illustrative of the scope and direction of current research in sedimentological and geochemical studies of organic/inorganic interaction.
Advective diagenesis predicts that large-scale mineral migration will occur when saturated pore fluids move across isotherms (or isobars). A general picture of the change in a given porosity field can be calculated if the fluid flow and temperature (or pressure) fields are known. For more detailed analysis it is necessary to know the details of the chemical equilibria involved, their temperature and pressure dependence, the host rock mineralogy and, in particular, the thermal mass transfer coefficients for the phases involved. In this paper thermal mass transfer coefficients for quartz and calcite have been calculated in detail over the temperature...
