The present is a key to the past: expanding terrestrial paleoclimate records with help from modern terrestrial carbonates
Terrestrial carbonates form in a variety of depositional environments, and have the potential to yield critical information about the response of continental climate to global climatic and tectonic events. For example, newer isotopic tools like clumped isotope thermometry can provide both estimates of temperatures in the ancient environments, as well as estimates of the d18O of the water the carbonates formed from. To use these new tools most accurately, however, we must understand more about the drivers of carbonate formation in modern environments. In this talk, I will present results from our modern-to-ancient studies of carbonate-producing soils and wetlands, discuss what we have learned about the drivers of carbonate formation in these environments, and the implications these modern data have on our paleoclimate records from these environments.
