Presentation transcript:

The Development of the Sulfur Isotopic Composition of Carbonate Associated Sulfate as an Indicator of Diagenetic Environment in the Formation of Dolomite Peter K Swart, Division of Marine Geology and Geophysics, Rosenstiel School of Marine and Atmospheric Science, Miami Fl 33149 Our approach is to use the S isotopic composition of trapped sulfate within the carbonate mineral as an indicator of the environment of diagenesis. The attached example shows the decrease in CAS in bulk sediment downcore.
