Paleoaltimetry from "clumped" ^(13)C-^(18)O bonds in carbonates, Colorado Plateau

Abstract

The elevation history of Earth's surface is a key element linking tectonic, geodynamic, climatic, and surface processes, but remains difficult to reconstruct from the geologic record. In contrast to conventional stable isotope paleoaltimetry approaches, the new "clumped" ^(13)C-^(18)O paleothermometer independently determines carbonate growth temperature and the δ^(18)O of water from which the carbonate grew, potentially enabling the effects of altitude, climate, and seasonality to be distinguished. This approach has been successfully applied to paleosol nodules. Here, we examine what other materials may potentially access paleoelevation information using this technique, including gastropods, the bivalve anomia, oysters, barnacles, soil, marl, and limestone from Cretaceous to Pliocene deposits from and adjacent to the Colorado Plateau, southwestern USA.
