How is climate written in the sedimentary record? Of the arsenal of tools available to approach this problem, experimental geochemistry is at once the most powerful and least utilized in Earth history and sedimentary geology. To gain unique insight into ancient (and modern) climate, the DPhil student will use experimental methods to link process to product in sedimentary systems. Using constraints from the sedimentary record, the goal is to re-animate geochemical systems to reveal links between mineral stability and climate and to establish the mineralogical, trace element and isotopic fingerprints of these interactions. The approach acts as a key link between sedimentary geology, palaeobiology, the mineral sciences and multiple sub-disciplines of geochemistry, and involves both labratory and field work. Research in our group currently ranges from understanding the co-evolution of life and environment through the Precambrian, the nature of early climate as recorded in the martian sedimentary record, as well as how chemical sedimentation occurs in modern analog environments.
