New Miocene “carbonate crash” paper

Colleagues working on the Miocene portion of IODP Exp. 353 cores (Site U1443), including Emmeline Gray and Clara Bolton, have found further evidence for a Miocene “carbonate crash” spanning the paleo-tropics.

By combining data from stable isotope and XRF elemental analyses, this new paper sheds light on global changes in the intensity of chemical weathering and riverine input of calcium and carbonate ions from ~13 –8 million years ago.
