Reinterpreting the rock record of carbonates: Marine carbonates provide one of the most important archives of the Earth’s surface environment. Interpreting this record requires distinguishing between local versus global effects and addressing the diagenetic history of samples, both of which can be very challenging. I will present new isotopic tools to help resolve questions surrounding the creation, preservation, and representativeness of geochemical signals in carbonates. This work forms the basis for being able to test the robustness of proxies in ancient samples and to more effectively use the rich geological record of carbonate sediments for learning about Earth history.
