  • [Uncertainty and Sensitivity Analysis of Phosphorus Model …

     · For large shallow lakes, the importance of parameter sensitivity in diagenesis models is no less than for hydrodynamic and water quality models. For large shallow lakes, the calibration of sensitive parameters should, therefore, be given attention when simulating the phosphorus content of areas with complicated water quality and sediment distributions.

    These data support the shallow conditions for nodule diagenesis in Bollène. A phreatic environment is more probable given that in vadose conditions we should have observed meniscus cements and because massive calcrete such as observed in the study area generally forms in a groundwater environment (e.g., Alonso-Zarza, 2003).

  • Diagenesis and Porosity

    Thus, diagenesis is greatest near the sediment surface and during shallow burial, where most variation in mineralogic composition of the carbonates and ground waters occurs (figure below). As carbonate s are buried more deeply, they are commonly in equilibrium with the adjacent subsurface waters; nevertheless, significant diagenetic changes can occur.

    Formation and Diagenesis of Carbonate Sediments. Morse, J. W. Abstract. Carbonate minerals in modern marine sediments can readily be divided into those found in shoal-to-shallow and deep-water environments.
