Evaluation of Early Diagenesis in Modern, Shallow-Water Carbonate Sediments by Mineralogy, Fabric and Porewater Geochemistry.

Abstract

Mineralogy, fabric and porewater geochemistry were examined in order to study early diagenesis in modern, shallow-water carbonate sediments of Key West area. The evidence for early diagenesis is visible as micritic cement in SEM images of sediment samples. Because the major cation concentrations are found to be insensitive to the diagenetic reactions in the study area, mineralogy instead of porewater geochemistry will be used to quantify the extent of early diagenesis. Rietveld crystal structure refinement method will be used for the accurate quantification of phase transformations. (MM)
