We are developing long-term climate records from the stable isotopes of paleosols, paleolake sediments, and weathered ashes in an effort to understand how climate and tectonics are linked in the North America Cordillera.  Working with collaborators Profs. Stephan Graham (Stanford), Chris Poulsen (Univ. of Michigan), Andreas Mulch (Univ. of Frankfurt), and Todd Ehlers (Univ. of Tuebingen ) we are using a wide range of techniques – such as climate models, stable isotope data, sedimentologic and cooling age studies to tease out these interactions. Recent work has been published in Geology (Mix et al., 2011),  American Journal of Science (Chamberlain et al., 2012Feng et al., 2013Mulch et al., 2015), Geochimica et Cosmochimica Acta (Mix and Chamberlain, 2014), Tectonics (Methner et al., 2015Methner et al., 2016), Proceedings of the Royal Society of London B: Biological Sciences (Eronen et al., 2015) and Geological Society of America Bulletin (Mix et al., 2016).
