Surficial Processes/Quaternary Studies

Professor John Dixon's research interests lie primarily in the area of Critical Zone processes and landscape evolution.  He is interested in the nature and rates of chemical weathering in Arctic and alpine environments.  Since 1990 he and his research teams have worked in Scandinavia, especially in Swdish and Norwegian Lapland, as well as in the Jotunheimen of southern Norway.  In addition he is also interested in regolith processes in arid environments, especially in the genesis and environmental significance of relict soils.

Surficial processes operating on Earth-like planets and their moons is also a focus of the surficial process research conducted in the department. The origin of gullies and other viscous flows on Mars and landscape evolution on Titan are investigated through planetary remote sensing and laboratory simulations under planetary environmental conditions.
