Welcome to the Rooney Geochronology and Geochemistry Group! We are a part of the Yale Metal Geochemistry Center. Our group utilizes the Re-Os geochronometer as well as Sr and Nd isotopes in conjunction with mineralogy, field mapping, sedimentology and stratigraphy to investigate climatic, biologic and tectonic transitions in earth’s history. Current projects involve resolving spatial-temporal Quaternary ice sheet dynamics and understanding and refining the timing of biological innovation, extinction and ice ages in the Neoproterozoic and Ordovician.
