Revisiting the Middle Eocene Climatic Optimum “Carbon Cycle Conundrum” With New Estimates of Atmospheric pCO2 From Boron Isotopes
Henehan, Michael J.; Edgar, Kirsty M.; Foster, Gavin L.; Penman, Donald E.; Hull, Pincelli M.; Greenop, Rosanna; Anagnostou, Eleni; Pearson, Paul N. (Paleoceanography and Paleoclimatology, 2020)The Middle Eocene Climatic Optimum (MECO) was a gradual warming event and carbon cycle perturbation that occurred between 40.5 and 40.1 Ma. A number of characteristics, including greater-than-expected deep-sea carbonate ... -
Secondary Minerals Drive Extreme Lithium Isotope Fractionation During Tropical Weathering
Chapela Lara, María; Buss, Heather L.; Henehan, Michael J.; Schuessler, Jan A.; McDowell, William H. (Journal of Geophysical Research: Earth Surface, 2022-02-15)Lithium isotopes are used to trace weathering intensity, but little is known about the processes that fractionate them in highly weathered settings, where secondary minerals play a dominant role in weathering reactions. ...
