Project A1 focuses on the reconstruction of paleo-latitudinal temperature gradients having prevailed on Earth during the contrasting atmospheric P(CO2) conditions of the Eocene and Maastrichtian. For this purpose, a wide range of fossil carbonates will be investigated for their clumped isotopic compositions (D47 and D48). The stable isotope facility at Goethe University is one of the very few labs in the world that is able to analyze D48 in high-precision along with D47. Dual clumped isotope analysis, for the first time, allows to deconvolve temperature from the kinetic information recorded in the single carbonate phase.
