The Rooney group seeks to understand the relationships between climate, tectonics, ocean geochemistry and evolution during critical transitions in Earth history.
Specifically, we use radiogenic isotope geochemistry in tandem with field geology to constrain interactions between the deep Earth and surface environments and the timing, rates and durations of geological events. n order to address such broad questions, the lab uses a wide-range of approaches (field geology, isotope geochemistry and geochronology).
