- 1 Intro
- 2 Talk layout: • Depositional setting: The Bahamian Margin Fluid-carbonate reactive exchange and its effects on geochemical records
- 3 Depositional Setting: Bahamian Margin • Platform margin sediment consists of re-deposited shallow marine sediments and pelagic material
- 4 Depositional Setting: Site 1003 ODP Site 1003 - Sampled on ODP Leg 166 in 1997
- 5 Shallow carbonate as a chemical archive? . Complicated - margin carbonate archives give conflicting, often contradictory geochemical signals to less complicated pelagic archives.
- 6 Fluid-sediment reactive exchange
- 7 The problem • Because sediments are progressively buried over time, recrystallizing sediments exchange with porefluids with different degrees of rock-buffering.
- 8 How to constrain reaction rate
- 9 Clumped isotopes: a one-slide primer
- 10 How to constrain recrystallization rate
- 11 Modeling variable reaction rate A single function for early and late diagenesis
- 12 How fast do fluids flow into margin?
- 13 A dataset for 84Ca on the Bahamian margin
- 14 Solving for advection rate
- 15 Fluid flow rates into the Bahamian margin
- 16 Correcting a 813C record for diagenesis
- 17 What can we do with these advection rates?
- 18 Carbon Isotopes on the platform margin
- 19 A consistent story?
- 20 Dissecting The problem • Diffusion rates are well-constrained experimentally
- 21 Summarizing the process . Carbonate and fluid geochemistry can be modeled over time. . This requires an understanding of reactive and advective behavior
