Laurence Coogan - Associate Professor
Dr. Coogan's research concentrates on understanding the processes that control heat and mass transfer from Earth's interior into the lithosphere and hydrosphere at mid-ocean ridges. His work spans a depth range from the mantle to the oceans, and addresses questions such as: What controls the amount of melt generated in the mantle at mid-ocean ridges? What is the composition of the upper mantle? How is the oceanic crust formed? How quickly does the oceanic crust cool? What are the heat and mass fluxes associated with hydrothermal cooling of new oceanic crust? These questions are answered using a combination of field and ship-board studies, petrology, high P-T experiments, analytical geochemistry, and modelling studies. In particular, Dr. Coogan has an interest in analytical techniques for in situ microanalysis and ICP-MS techniques. Dr. Coogan's other research interests include the mechanisms of igneous differentiation, the evolution of seawater chemistry over geological time and the processes controlling the cooling of Earth's mantle.
