Abstract:

The uplift, erosion, and weathering of mountain ranges can modulate Earth's climate over both short and geologic timescales. Uplift forms topographic barriers to atmospheric circulation and thus can influence climate over human lifetimes, while erosion and weathering influence ocean and thus atmospheric chemistry over millions of years. Geologists can now explore these linkages in remarkable detail using geochemical tools that have emerged over the last several decades. For example, isotopes contained in handful of sand collected from a river can reveal how mountains crumble under the forces of erosion and how the flux of eroded material to the oceans influences atmospheric chemistry and thus global climate. I will discuss several of the techniques that have led to these advances, with exciting case studies from the literature and my own work for illustration of how geochemical fingerprint can be used to solve cutting edge problems in the geosciences.
